The rules to subtract integers are discussed here.
If a and b are two integers, then to subtract b from a, we change the sign of b and add it to a;
a – b = a + (-b)
Consider the following examples for the rules to subtract integers.
1. 4 from 9
In order to subtract 4 from 9, we change the sign of 4 and add it to 9.
Thus, we have 9 – 4 = 9 + (-4) = 5.
2. -4 from 7
In order to subtract -4 from 7, we change the sign of -4 and add it to 7.
Thus, we have 7 – (-4) = 7 + 4 = 11.
3. 3 from -8
In order to subtract 3 from -8, we change the sign of 3 and add it to -8.
Thus, we have -8 – 3 = (-8) + (-3) = -11.
4. -9 from -5
In order to subtract -9 from -5, we change the sign of -9 and add it to -5.
Thus, we have -5 – (-9) = (-5) + 9 = 4.
