Question

Calcule o valor das expressões numéricas:
a) 20 - (6 - 2) = b) 10 + 5 x 2 - 3 x 3 + 4 x 2=

c) 32 - 4 x 3 - 5 x 3 + 2 x 6= d) (42 + 1 - 13) x (52 - 43 + 1)=

e) 20 + 12  4 - 1 = f) 72  8 + 5 x 3 - 2 =

g) (10 + 5) x 2 - (5 + 5)  2 = h) (6 x 3 + 2 x 2 + 5 x 0) + 12  3 =

i) 1000 - [(2 x 4 - 6) + (2 + 6 x 4)] = j) 60 + {[4 x (6 + 2) - 10] + 12} =
