Computation is the process to determine and calculate something through logical and mathematical methods. There are overall four operations that you will study, including Addition, Subtraction, Division and Multiplication. With the help of Computation operations, you will find the answers to various numerical problems.
To perform Addition, it is important to add the digits in one place. Simultaneously, you can carry it and then add the ten's place digits, etc.
It is commutative, and the order sometimes does not matter in it.
Which means 1+2 = 2+1, so they both are the same.
The addition is further Associative. It means the order will remain in the same grouping.
For e.g. 2+3+5 = 5+3+2
In Subtraction, it is essential to take one number and the amount from the other number. A Subtraction can neither be associative nor be commutative.
Subtraction is not associative.
(1-2)-3 is not equal to 1-(2-3)
In Multiplication, the number is added to itself a certain number of times. A Multiplication can be Distributive, Cumulative, and Associative and has an identity property.
For, e.g.
5*2 = 5+5
= 10
The division is the distribution over both the Subtraction and Addition. A Division can be left associative.
For, e.g.
(6+9) / 3 = (6 / 3) + (9 / 3)
15/3 = 2+3
5 = 5
LHS = RHS (Hence, proved)
