Question

How do i subtract integers/ what are the rules? ex. -5 - -12

Answer 1

Answer:

you keep flip change so the minus becomes addition and -12 becomes positive 12 so it turns out as -5+12 which is 7

Step-by-step explanation:

Answer 2

Answer: a - b = a + (- b). To subtract an integer from another integer, the sign of the number (which is to be subtracted) should be changed and then this number with the changed sign, should be added to the first number.

Let's understand the rule in detail.

Explanation:

The subtraction of integers is very much much similar to addition. It can be done as follows

1. Change the sign of the number to be subtracted and add them up.

2. The result takes the sign of the greater number

For example,

(-10) - (-12) = -10 + ( 12) = -10 + 12 = 2

2 - (-3) = 2 + (3) = 5

(+6) – (+2)  = (+6) + (-2) = 6 - 2 = 4

Thus, to subtract an integer from another integer, the sign of the number (which is to be subtracted) should be changed and then this number with the changed sign, should be added to the first number.
