Remember the order of operations rules. PEMDAS: parentheses first, then exponents, then multiplication, then division, then addition and subtraction is last.
= 42+6⋅52−33÷32
multiply first
= 42 + (6*52) - 33 ÷ 32
= 42 + 312 - 33 ÷ 32
division second
= 42 + 312 - 1.03125
addition next
= 354 - 1.03125
subtraction last
= 352.96875
ANSWER: 352.96875 (*if rounding, answer is 353)
Hope this helps! :)
