How to Divide Integers

We say that integers are the numbers which extend from minus infinite to plus infinite including zero. These numbers can be expressed on the number line.  Here we are going to learn about dividing integers. When we talk about  dividing integers properties, we say that the closure property does not hold true for the integers, which means that if we divide any integer number by another integer number, then the  result is not necessary an integer.
 Another property of integers is commutative property, which does not hold true for the division of the integer numbers.  Here we say that if a and b is any two integer numbers, then we say that a divided by b is not equal to b divided by a. mathematically we represent it as:
  A ÷ b  <> b ÷ a
 Now we say that  let us look at the  associative property of integers which also does not hold true for the division operation. We say that if we have a, b, c as any three integer numbers, then  we have :
( a ÷ b ) ÷ c <> a ÷ (  b ÷ c)

 Let us take another property of integers as division by 1: According to this property, we mean that if any integer number a is divided by 1, then the result is the original integer number so if we have a as any integer number, then we write it mathematically as  a ÷ 1 = a
 On the other hand, if any integer is divided by -1, then we write  a ÷ -1 = -a


 We will learn about the Trapezoidal Rule by taking online help from online math tutor. We can get CBSE sample papers online, which can help us to get the guide lines about how to prepare for the fore coming examination.

How to solve Pattern Worksheets

We can see different patterns and series around us in our daily life. These patterns  can be the patterns drawn on the print of a  shirt, Pattern of the growth of the petals of a flower, patterns of the flooring  in your school. We must understand the methods of the formation of patterns and the logics used in it. The patterns  formed in such a way are called logical patterns. Now we look at the different mathematical patterns formed.
Let us look at some of the following series:
2 , 4 , 6 , 8, 10, 12, .. . . . . . This is the pattern of the even natural numbers. We say that these numbers are divisible by 2
1, 3, 5, 7, 9, 11, 13, 15, 17 , . . . . . . . . . . .  This is the pattern of the  odd numbers. We say that these numbers are not divisible by 2. Another series we take is the series of  prime numbers.
2, 3, 5, 7, 11, 13, 17, 19, . . . . are all prime numbers. We say that the prime numbers are the numbers which are having only 2 factors i.e. 1 and itself.
Now we will look at the series 1, 4, 9, 25, 36, 49, . . . . . . We say that this series is the series of the numbers which are the squares of the natural numbers 1, 2, 3, 4 ,5 , 6, . . . . . etc.
We can form infinite number of such series which can be in the form of Factorials, A.P. , G.P. etc.

 We can learn about Pattern Worksheets online and practice about the different types of patterns available or which can be formed. To learn about the Differential Equations we must go through CBSE Books for Class 11.

Subtracting Integers

In the previous section we have discussed about adding scientific notation calculator and In today's session we are going to discuss about Subtracting Integers.
We know that the subtraction operation is to be performed when something is to be reduced from the given unit. Now we will learn how to perform the operation of subtraction. Here we will learn it by the help of the following expression:
Subtract -5 from -7
 In this expression, we observe that both the terms are negative. So the given expression can be mathematically expressed as follows:
 = -7 – ( -5 ), so we come to the conclusion that the sign of the second term will be changed when we perform subtraction. So we get “
 = -7 + 5
= -2, here the sign of the second term becomes positive and thus we get the result by performing the addition operation between the two terms as -2.  When we need to learn about Quotient Rule, we must go through the cbse textbooks for class 11 and understand the basic concepts for the same. Now we will find that we perform the subtraction operation between the terms such the subtrahend is a negative number and the minuend is a positive number, then we proceed as follows:
 Subtract -4 from + 6, so this expression will be written as follows:
 = 6 – ( -4 ), so we write that the  sign of the negative number -4 will change to  + 4 and the expression will be written as follows :
= 6 + 4 = + 10
Thus we find the two terms will be added up and we get the result as  + 10, which is the difference of the  two numbers  where the  subtrahend is a negative number and the minuend is a positive number.

adding scientific notation calculator

In simple terms a scientific notation is a way of writing numbers which are too large or too small and can be written in standard decimal notation. Scientific notation has the number of useful properties which are more commonly used in calculators and also by the mathematicians, engineers and scientists. Exponential notation is the other name of scientific notation. In scientific notation all the numbers are written in the form of
  a * 10^b  ; where the b in the exponential form is the integer, the coefficient a is any real number in other words the number 10 is also known as base. Power of ten notation is used to save our efforts. If the decimal moved to the left this means base has the positive exponent. And if it has negative exponent it will move to the right.
There are few steps can be followed to add and subtract any two numbers in the adding scientific notation calculator.
Step 1 is to adjust the power of 10 in the 2 number so that they can form the same index.
Step 2 is to add or subtract the number
step 3 is to give the answer in the scientific notation.
Now we will understand this with the help of the following instance.
Evaluate 3 * 10³ + 6.3 * 10⁴ and give your answer in the scientific notation.
Solution : 3 * 10³ + 6.3 * 10⁴

= 0.3 * 10⁴ + 6.3 * 10⁴ ( convert them into the same indices)

= (0.3 + 6.3 ) * 10⁴ (add the numbers)

= 6.6 * 10⁴ ( answer in scientific notation.)

subtracting integers worksheet

Previously we have discussed about antiderivative of e and In today's session we are going to discuss about subtracting integers worksheet, We know that integers are all natural numbers, their negative numbers & zero. Since we can do mathematical operations of addition, subtraction, multiplication & division, so we can do all these operations on integers as well. We can further improve our skills by working out subtracting integers worksheet.
Let us know how to subtract integers. We know that on a number line 0 is placed in the centre , all positive numbers on the right side of zero in increasing order & all negative numbers on left side of zero in decreasing order. To subtract any two integers, we can use a number line or can do the same by following the rules of signs associated with integers.(Know more about integers in broad manner, here,)
To subtract the given integers, we first consider their signs. If the two integers to be subtracted have positive sign, we subtract the smaller  number from the bigger & put +ve sign before the answer if smaller number is to be subtracted, while a –ve sign is put if the bigger number was to be subtracted. E.g., 3-7= -4 as 7, the bigger number was to be subtracted. But if it was 7-3, the answer would be 4 as the smaller number is to be subtracted.
While subtracting a –ve number, the –ve sign of the number & the minus sigh together become +, so we actually add the two numbers, e.g., 4-(-9)=4+9=13
To subtract a positive number from a negative number, the two numbers are actually added & a –ve sign is put before their sum, e.g.,(-8)-5=-8-5=-13.
Thus, we see that all the rules relating to addition of integers are followed in subtraction also with the only difference that the minus sign of subtraction combines with the sign of the number to be subtracted & for this combination of the sighs, we follow the following pattern:
-ve & +ve become –ve
-ve & -ve become +ve

We could also learn new topics like Binomial distribution and its also an important topic in andhra pradesh education board.
In the next session we will discuss about Properties of Numbers and  if anyone want to know about factor algebra calculator then they can refer to Internet and text books for understanding it more precisely.

Properties of Irrational Numbers

Previously we have discussed about factoring perfect square trinomials worksheet and In today's session we are going to discuss about Rational and irrational numbers which comes under board of andhra pradesh intermediate, They are the different type of number representation in the number system of mathematics. These are the number representations which help in solving the problem related to math. If we define the rational numbers then we can say that rational numbers are those numbers which represent the integer value in the form of numerator and denominator. For example, x / y, here x is numerator and y indicates the denominator which should be greater then 0.

In the same sense we can say that irrational numbers are those numbers which can’t be represented in the form of numerator and denominator format. In the general sense irrational numbers in the number system can be considered as real numbers but they can’t be shown in fractional format. The fundamental properties of irrational number is that they can’t be represented in ratio form.Through this topic we are going to discuss about the Properties of Irrational Numbers. Let's explain the concept to you with the help of some examples.

The famous example of irrational numbers is ∏. Generally this symbol is known as ‘ pi ‘. In the mathematics pi value is approximated as 22 / 7. It means ∏ = 3.141592653589 and so on. In the value of pi , we can see that the value is not accurate or they can’t be represented in standard fractional format. Thus, one of the Properties of Irrational Numbers is that the cannot be represented in fractional form. (Know more about  Irrational Numbers in broad manner, here,)

Another famous example of irrational numbers are √2. In the √2 there actual value is 1.41421356 and so on. As like the another fractional number √2 can’t be represented using ratio property of two numbers and they can’t be represented in any simple faction. That’s why this is irrational number.

Even the number e (symbol of Euler number ) can’t be represented in the ratio form and in simpler fraction from.

Binary Numbers

Previously we have discussed about how to solve limits and In today's session we are going to discuss about Binary numbers that comes under board of ssc education andhra pradesh, It deals with only two numbers 0 and 1.it is also known as base-2 number system. It has a radix of 2. In todays gadgets and computers, the circuits are implemented using binary coding that uses Binary Numbers.The main reason is that it is easy to manipulate the equations with 0 and 1.
We can define Binary Numbers as the ones that contain only two digits: 0's and 1's.
00000011001011011101010111 is a binary number. We can define Binary numbers as a sequence of 0's and 1's. The binary number can be converted into decimal numbers and hexadecimal numbers using the conversion formulas. Any number can be represented in the form of 0 and 1 and can be converted back into its original form .
Counting in binary number starts by taking rightmost digits and moving toward left. Conversion of binary number can be converted to decimal number by multiplying each digit by the corresponding power of 2.
for example,

0 0 1 1 can be converted to decimal number as,

[ 0 0 1 1 ]₂ =[ ( 2⁰ * 1 ) + ( 2 ¹ * 1 ) + ( 2² * 0 ) + ( 2³ * 0 ) ]₁₀
= [ 1 + 2 + 0 + 0 ]₁₀
=[3]₁₀

Similary, we can convert any binary number to a decimal number.
Following is the table which shows binary numbers and their corresponding decimal numbers.

Binary number decimal number

0 0
1 1
1 0 2
1 1 3
1 0 0 4
1 0 1 5
1 1 0 6
1 1 1 7
1 0 0 0 8
1 0 0 1 9

Now. Let us do addition in of binary numbers.
There are following rules,
1 + 1 =1 0
1 + 0 = 1
0 + 1 = 1
0 + 0 = 0

let us add two binary numbers,

1 0 1 0 + 1 1 0 0

1 0 1 0
+1 1 0 0
---------------------------------------------
1 0 1 1 0

we can implement a binary adder using this rule.
