Question

Calcule as expressões abaixo:

a) |3−(−8)|

b) −5−||3|∗17|

c) |3|−|−8|+|17|−|−5|

d) |3∗(19)|−(4)∗|19+3|−(−5)

Answer 1

a) |3−(−8)| = 3 + 8 = 11

b) −5−||3|∗17| = - 5 - (51) = - 5 - 51 = - 56

c) |3|−|−8|+|17|−|−5| = 3 + 8 + 17 + 5 = 11 + 22 = 33

d)
= |3∗(19)|−(4)∗|19+3|−(−5)

= 57 - 4.22 + 5 = 57 - 88 + 5 = 62 - 88 = - 26
