AS EXPRESSÕES NUMÉRICAS - GABARITO
EXERCÍCIOS.
1) Resolva as expressões numéricas.
a) 12 x 8 – 4 + 12 = b) 100 ( 5 – 1 + 8 = c) 36 x 24 ( 6 + 2 =
d) 22 + 34 ( 17 – 15 = e) 52 – 26 ( 13 + 10 = f) 1000 – 30 x 10 + 1002 =
2) Resolva as mesmas expressões observando os parênteses.
a) 12 x (8 – 4) + 12 = b) 100 ( (5 – 1) + 8 = c) 36 x (24 ( 6 + 2) =
d) 12 + 34 ( (17 – 15) = e) (52 – 26) ( 13 + 10 = f) (1000 – 30) x (10 + 1002) = 
3) Coloque os parênteses de forma que as expressões sejam verdadeiras.
a) 2 x (5 + 6 – 1) = 20 b) 36 ( (12 + 3 x 2) = 2 c) (12 ÷ 4) x (5 – 1) = 12 
d) 102 x (2 – 1) = 102 e) (23 – 2) x (2 + 4) = 126 f) 100 ( (4 x 6 + 1) = 4
4) Desafio: [125 – 12 x (64 ÷ 8 + 2)] =
