Whole Numbers

Given any number, we can easily find the successor and predecessor of the number by using certain formulae. If we need to find the successor of any number, we just need to add one to the number. This gets us the successor of the number. Whereas, if we need to find the predecessor of the number, we just need to subtract one from the number. This gets us the predecessor of the number. Before going into the crux of the matter we need to know the meaning of whole numbers. Basically, whole numbers are the set of natural numbers along with zero. To find whole numbers, we use different operations such as addition, subtraction, multiplication, and division. To solve these types of sums we need to use the number line.

A number line is a representation of all the real number. The distance between all the different points is known as unit distance.

We need to different laws to be able to solve certain types of sums:

  • Closure property :- This property tells us how whole numbers are closed under addition and multiplication.
  • Commutative property :- This property tells us how we can add and multiply whole numbers in any order.
  • Associative property :- {(2+3)+4=5+4=9}

Example:=>
{123(14-10)+112(22-11)-99(10-6)}
Simplify:=>
 \smallskip {123(14-10)+112(22-11)-99(10-6)} \\ \smallskip {\:=\:123(4)+112(11)-99(4)} \\ \smallskip {\:=\: 492+1232-396} \\ \smallskip {\:=\:1328}
