OpenStudy (johnweldon1993):

Actually the answer is 4 [(21 + 6) - 3²] ÷ 9 · 2 inside parenthesis [(27) - 3²] ÷ 9 · 2 Finish the brackets (27 - 3²) ÷ 9 · 2 Now exponents (27 - 9) ÷ 9 · 2 Parenthesis 18 ÷ 9 · 2 Since it is only division and multiplication left you go from left to right 18 ÷ 9 = 2 2· 2 = 4
