To avoid confusion, remember PEMDAS. This is the order of operation. Parenthesis, Exponents, Multiply, Divide, Add, Subtract 21 ÷ 7 + 20 * 102 * 2 - 3 No parenthesis and no exponents, proceed to multiplication. 20 * 102 * 2 = 4,080 Then, perform division 21÷7 = 3 Then, do addition 3 + 4080 = 4083 Lastly, do subtraction 4,083 - 3 = 4,080 So, 21 ÷ 7 + 20 * 102 * 2 - 3 = 4,080
