Select all the true statements. A. 2 + (−2) is equal to zero.

B. (−3) + (−4) is positive.

C. −2 − (− 2) is positive.

D. 5 + (−2) is positive .

E. 7 − (−10) is negative.

A and D

Step-by-step explanation:

A. 2 + (−2) = 2 - 2= 0, true.

B. (−3) + (−4) = - 3 - 4 = -7 is negative, False

C. −2 − (− 2) = -2 + 2 = 0, neither positive nor negative, false.

D. 5 + (−2) = 5 - 2 = 3,is positive true.

E. 7 − (−10)= 7 + 10 = 17  is psoitive, false

options : A, D

so, converting firstly the mixed fractions to improper fractions and then "adding".
