$36+12\div(3+3)+6\cdot2=50$
For these questions, trial and error will help get the correct use of parenthesis. 1) Use brackets and parenthesis to make it clear which steps need to be done first. 2) We solve the expressions within the brackets first and then move to division, then multiplication, and then addition. $36+12\div(3+3)+6\cdot2=50$ $36+12\div(6)+6\cdot2=50$ $36+2+12=50$ $50=50$
