FOUR BASIC ARITHMETIC OPERATIONSReview of Introductory MathematicsHierarchyofMathematicalOperationsMathematical operations such as addition, subtraction, multiplication, and division are usuallyperformed in a certain order or sequence. Typically, multiplication and division operations aredone prior to addition and subtraction operations. In addition, mathematical operations are alsogenerally performed from left to right using this heirarchy. The use of parentheses is alsocommon to set apart operations that should be performed in a particular sequence.Example:Perform the following mathematical operations to solve for the correct answer:(2 + 3) + (2 x 4) + ( ) = __________622Solution:a. Mathematical operations are typically performed going from left to right withinan equation and within sets of parentheses.b. Perform all math operations within the sets of parentheses first.2 + 3 = 52 x 4 = 8Note that the addition of 6 and 2 was performed prior to dividing622824by 2.c. Perform all math operations outside of the parentheses. In this case, add from leftto right.5 + 8 + 4 = 17Example:Solve the following equation:(4 - 2) + (3 x 4) - (10 ÷ 5) - 6 = ______Solution:a. Perform math operations inside each set of parentheses.4 - 2 = 23 x 4 = 12MA-01 Page 16 Rev. 0
