Question

Вычислите: а)-13-17+12+18 б)-15+50-25-20 в)19-30-31-22 г)-89-90-91-92

Answer 1

А) -13-17+12+18= -30+30= 0
б) -15+50-25-20 = -60+50= -10
в)19-30-31-22 = -83+19 = -64
г) -89 - 90-91-92 = -180 - 182 = -362

Answer 2

Calculation:

Let's calculate the given expressions step by step:

a) -13 - 17 + 12 + 18

-13 - 17 + 12 + 18 = -30 + 30 = 0

b) -15 + 50 - 25 - 20

-15 + 50 - 25 - 20 = 35 - 45 = -10

c) 19 - 30 - 31 - 22

19 - 30 - 31 - 22 = -64

d) -89 - 90 - 91 - 92

-89 - 90 - 91 - 92 = -362

So, the calculations are as follows:

a) -13 - 17 + 12 + 18 = 0 b) -15 + 50 - 25 - 20 = -10 c) 19 - 30 - 31 - 22 = -64 d) -89 - 90 - 91 - 92 = -362
