Question

A) 72-5x(27:3-6) =


B) (20:5+3)x22 =

C) 33:{10+[6:3+(1+2)]-4} =

D) 120+{560:[40+(300:10)]-19 =

E) 360:{100-[50-(2x3+4)]}+40 =

Answer 1

$a) \\ 72 - 5 \times ( \frac{27}{3 - 6} ) \\ 72 - 5 \times \frac{27}{ - 3} \\ 72 + 5 \times 9 \\ 117$
$b) \\ ( \frac{20}{5 + 3} ) \times 22 \\ \frac{20}{8} \times 22 \\ \frac{5}{2} \times 22 \\ 5 \times 11 \\ 55$
$c) \\ \frac{33}{(10 + ( \frac{6}{3 + ( 1 + 2)}) - 4) } \\ \frac{33}{(10 + \frac{6}{6} - 4)} \\ \frac{33}{7}$
$d) \\ 120 + \frac{560}{(40 + ( \frac{300}{10})) } - 19 \\ 120 + \frac{560}{40 + 30} - 19 \\ 120 + \frac{560}{70} - 19 \\ 120 + 8 + 19 \\ 109$
$e) \\ \frac{360}{100 - (50 - (2 \times 3 + 4))} + 40 \\ \frac{360}{100 - (50 - 10)} + 40 \\ \frac{360}{60} + 40 \\ 6 + 40 \\ 46$
