I
a) (-5)(-4) (-3) =
b) 12 - 8 + 15 - 2 + 13+ 4-2 =
c) (3 + 7) (-4-9 ) =
d) - 2-6-8 - 12 - 18 =
e) 21 + 7-(2)(-1) = ​

Answer 1

Explicación paso a paso:

a) (-5)(-4) (-3) = 20(-3) = -60

b) 12 - 8 + 15 - 2 + 13+ 4-2 = 4+13+11+2 = 17+13 = 30

c) (3 + 7) (-4-9 ) =(10)(-13) = -130

d) - 2-6-8 - 12 - 18 = -8-20-18 = -28-18 = -46

e) 21 + 7-(2)(-1) = 28-(-2) = 28+2 = 30
