Question

What is the sum?8+(-12)O-200440 40 20

Answer 1

-4

First let's state what we are given:

`\text{ 8 + (-12)}`

To find the sum, we would open the bracket by applying the multiplication of opposite sign rule.

Note: The multiplication of same signs give a positive sign.

The multiplication of opposite signs give a negative sign.

In our question, we have negative signs: The + sign outside and the - sign inside the bracket.

After multiplying:

`\text{ = 8 - 12}`

Then we would solve:

`\text{ = -4}`

Therefore, the sum of 8+(-12) is = -4
