Question

a) 12+56: 8+36=
b) 100:50+5*5+8*6=
c) 100*7-10*5+8*9=
d) 16*4+8:2-4*2=​

Answer 1

a)

$12 + 56 \div 8 + 36 = \\ 12 + 7 + 36 = \\ 19 + 36 = 55$

b)

$100 \div 50 + 5 \times 5 + 8 \times 6 = \\ 2 + 25 + 48 = \\ 27 + 48 = 75$

c)

$100 \times 7 - 10 \times 5 + 8 \times 9 = \\ 700 - 50 + 72 = \\ 650 + 72 = 722$

d)

$16 \times 4 + 8 \div 2 - 4 \times 2 = \\ 64 + 4 - 8 = \\ 68 - 8 = 60$
