Question

1. Considerando x = +6552, y = -1989 e z= -13, calcule:
a) (x - y): 2
c) X:4 - 2
b) 3.y:z

Answer 1

a) [6.552 - (-1.989)] ÷ 2. 6.552 + 1.989 = 8.541. 8.541 ÷ 2 = 4.270,5

c) 6.552 ÷ 4 - 2. 6.552 ÷ 4 = 1.638. 1.638 - 2 = 1.636.

b) 3 × (-1.989) ÷ (-13). 3 × (-1.989) = -5.967. -5.967 ÷ (-13) = 459.
