Question

How do you subtract an integer from another integer without using a number line or counters? Give an example.

Answer 1

Explanation:

Additive inverse is the opposite of a number; the sum of additive inverses is zero. An integer and its additive inverse make up a zero pair.

example: 3

integer: -3+3=0

additive inverse: 3-3=0

Hope this helps!

Thanks!

Answer 2

The General rule for adding and subtracting numbers
1. Two integers with the same signs
Once 2 integers has the same sign, then just add the numbers.
For example
1. 1+1 = 2
2. 2 + 5 = 7

2. Two integers with different signs
When 2 integers has different sign, then find the difference
For example
1. 1-1 =0
2. 2 – 5 = -3

3. Two integers that vary in sign
When 2 integers vary in sign, then it will depend who which number carries the largest value
For example
1. -3 + 2 = -1
2. 2 – 1 = 1
