Explicação passo-a-passo:

$49 - (6 \times 6 - 15) + 7 = \\ 49 - (36 - 15 + 7 \ \\ 49 - 21 + 7 \\28 + 7 \\ 35$

$94 + 25 \times 4 - (30 \times 2) + 8 + 6 \\ 94 + 25 \times 4 - 60 + 8 + 6 \\ 94 + 100 - 60 + 8 + 6 \\ 194 - 60 + 8 + 6 \\ 134 + 8 + 6 \\ 142 + 6 \\ 148$

$75 - (15 \times 4) + (74 + 36) + 21 + 2 \\ 75 - 60 + (74 + 36) + 21 + 2 \\ 75 - 60 + 110 + 21 + 2 \\ 15 + 110 + 21 + 2 \\ 125 + 21 + 2 \\ 146 + 2 \\ 148$

$(4 + 6 \times 6) - 5 \times 8 - 2 \\ (4 + 36) - 5 \times 8 - 2 \\ 40 - 5 \times 8 - 2 \\40 - 40 - 2 \\ 0 - 2 \\ - 2$

$25 + (15 + 6 \times 3) \times 5 - 10 \\ 25 + (15 + 18) \times 5 - 10 \\ 25 + 33 \times 5 - 10 \\ 25 + 165 - 10 \\ 190 - 10 \\ 180$
