You are given 42+3-2(3), 22(8)÷2+2, (42+16)+12 and 8(32)+3. You are asked to simplify each expression using the order of operations. In solving this, use PEMDAS (parenthesis, multiplication, division, addition, subtraction), the order in which you can solve these expressions. The answers are:
42+3-2(3) = 39
22(8)÷2+2 = 90
(42+16)+12 = 70
8(32)+3 = 259
