Question

Resolva as expressões ​

Answer 1

Resposta:

$6 \times 1 \times 3 \\ 6 \times 1 = 6 \\ 6 \times 3 = 18$

$2 \times 9 \times 1 \\ 9 \times 1 = 9 \\ 2 \times 9 = 18$

$(5 \times 1) \times 3 \\ 5 \times 1 = 5 \\ 5 \times 3 = 15$

$3 \times 2 \times 5 \\ 2 \times 5 = 10 \\ 3 \times 10 = 30$

$4 \times (2 \times 5) \\ 2 \times 5 = 10 \\ 4 \times 10 = 40$

$13 + 2 + 5 \\ 13 + 2 = 15 \\ 15 + 5 = 20$

$9 - 4 - 1 \\ - 4 - 1 = - (4 + 1) = - 5 \\ 9 - 5 = 4$

$(9 + 2) + 3 \\ 9 + 2 = 11 \\ 11 + 3 = 14$

$9 - (8 - 4) \\ 8 - 4 = 4 \\ 9 - 4 = 5$

$10 + (6 + 3) \\ 6 + 3 = 9 \\ 10 + 9 = 19$
