Question

Evaluate the following: −3 − (−2). (5 points) a. -5 B. -1 c. 1 d. -6

Answer 1

B:-1

Explanation:

-3-(-2)=-3+2=-1

Answer 2

-1

Explanation:

`- 3 - ( - 2)`

When there is a (-) in front of an expression in parentheses, change the sign of each term in the expression

`- 3 + 2`

Here, 3 > 2 , So, we have to enter the sign of 3 which is negative.

Calculate:

`- 1`

Some rules:

`( + ) * ( + ) = ( + )`

`( + ) * ( - ) = ( </strong><strong>-</strong><strong> )`

`( - ) * ( - ) = ( </strong><strong>+</strong><strong> )`

`( - ) * ( + ) = ( - )`

Hope this helps..
