| Multiplication of Integers | Additive Inverse | Subtraction of Integers | Before you study How to do Subtraction of Integers.
You must know :-
What is additive inverse ? (topic available in this site)
How to do Addition of integers ? (topic available in this site)
Explanation :-
In the process of subtraction of integers, simply add the additive inverse of the integer that is to be subtracted, from the other integer.
Study the Subtraction of Integers with the help of following examples :-
Example 1 = (+4) - (+7)
Answer = (+4) - (+7)
The additive inverse of (+7) is (-7) and on addition of the additive inverse we will get,
= (+4) + (-7)
Subtract the integers and answer will contain (-)sign because the bigger integer(-7) is a negative integer.
= -3
Example 2 = (+20) - (-8)
Answer = (+20) - (-8)
The additive inverse of (-8) is (+8) and on addition of the additive inverse we will get,
= (+20) + (+8)
Subtract the integers and answer will contain (+)sign because the bigger integer(+20) is a positive integer.
= +28 or = 28
Example 3 = (42) - (27)
Answer = (42) - (27)
The additive inverse of (27) is (-27) and on addition of the additive inverse we will get,
= (42) + (-27)
Subtract the integers and answer will contain (+)sign because the bigger integer(+20) is a positive integer.
= +15 or = 15
Example 4 = (-25) - (-35)
Answer = (-25) - (-35)
The additive inverse of (-35) is (35) and on addition of the additive inverse we will get,
= (-25) + (+35)
Subtract the integers and answer will contain (+)sign because the bigger integer(+20) is a positive integer.
= +10 or = 10
Example 5 = (-49) - (-35)
Answer = (-25) - (-35)
The additive inverse of (-35) is (35) and on addition of the additive inverse we will get,
= (-49) + (35)
Subtract the integers and answer will contain (-)sign because the bigger integer(-7) is a negative integer.
= -14
