Answer 1

А)13-(-2)=15б)-4-(-8)=4 в)5-(-9)=14 г)-12-(-5)=7

Answer 2

А)13+2=15 б)-4+8=4 в)5+9=14 г)-12+5=-7

Answer 3

Let's solve the expressions step by step:

А) 13 - (-2) To subtract a negative number, we can change it to addition: 13 + 2 = 15

Б) -4 - (-8) To subtract a negative number, we can change it to addition: -4 + 8 = 4

В) 5 - (-9) To subtract a negative number, we can change it to addition: 5 + 9 = 14

Г) -12 - (-5) To subtract a negative number, we can change it to addition: -12 + 5 = -7

So the results are: А) 15 Б) 4 В) 14 Г) -7
