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.
