B.

+8

C.

-16

D.

+16

#### SOLUTION

(+12)+(-4) = 12 - 4 = 8 If white buttons represent positive integers and black buttons represent negative integers. Find the net value of all the buttons shown:

A.

+1

B.

-1

C.

0

D.

7

#### SOLUTION

Solution : B

According to the problem,
There are 4 black buttons = -4
There are 3 white buttons = 3
