Answer
$(36 + 12) \div (3 + 3) + 6 \times 2 = 20$
Work Step by Step
Note: For these questions, trial and error might help.
1) Use brackets and parenthesis to make it clear which steps need to be done first.
2) Follow BEDMAS in Step #3: Division goes first, then multiplication, and finally addition.
$36 + 12 \div 3 + 3 + 6 \times 2 = 30$
$(36 + 12) \div (3 + 3) + 6 \times 2 = 20$
$[(48) \div (6)] + (6 \times 2) = 20$
$[8] + (12) = 20$
$20 = 20$
