Answer 1

Ответ:

-5+2=(-3)

-7+4=(-3)

-7-4=(-11)

5+(-9)=(-4)

-4+(-3)=(-7)

-8+2=(-6)

6+(-10)=(-4)

-18+7=(-11)

-18+20=2

9-11=(-2)

Answer 2

Let's solve each of these arithmetic expressions one by one:

-5 + 2 = -3 -7 + 4 = -3 -7 - 4 = -11 5 + (-9) = -4 -4 + (-3) = -7 -8 + 2 = -6 6 + (-10) = -4 -18 + 7 = -11 -18 + 20 = 2 9 - 11 = -2

Therefore: -5 + 2 = -3 -7 + 4 = -3 -7 - 4 = -11 5 + (-9) = -4 -4 + (-3) = -7 -8 + 2 = -6 6 + (-10) = -4 -18 + 7 = -11 -18 + 20 = 2 9 - 11 = -2
