Answers

  1. Using the order of operations, the expression can be simplified as  
    9 + 1.34 + 62.88 = 73.22
    The order of operations instructs us on how to solve steps in multi-step expressions. Any operations contained within parenthesis or brackets are first solved. After that, we handle any exponents. Third, we perform all division and multiplication operations from left to right. Fourth, all addition and subtraction problems are solved from left to right.
    Remember PEMDAS when simplifying multi-step expressions, i.e.:
    P (Parentheses)
    E (Exponents, Powers and Square Roots)
    MD (Multiplication and Division, left-to-right)
    AS (Addition and Subtraction, left-to-right)
    The expression given in the problem is:  9 + 1.34 + 1 2 (3.50 +1.74)
    Apply the above operation order:
    Step 1: solve the addition inside the parenthesis
    9 + 1.34 + 1 2 (3.50 +1.74)  =  9 + 1.34 + 1 2 (5.24)
    Step 2: Multiply the result by 12
    9 + 1.34 + 1 2 (5.24) = 9 + 1.34 + 62.88
    Step 3: Apply addition from left to right
    9 + 1.34 + 62.88 = 73.22
