Review of Introductory Mathematics FOUR BASIC ARITHMETIC OPERATIONS10 ÷ 5 = 2b. Perform addition and subtraction operations from left to right.c. The final answer is 2 + 12 - 2 - 6 = 6There may be cases where several operations will be performed within multiple sets ofparentheses. In these cases you must perform all operations within the innermost set ofparentheses and work outward. You must continue to observe the hierarchical rules through outthe problem. Additional sets of parentheses may be indicated by brackets, [ ].Example:Solve the following equation:[2 ( 3 + 5) - 5 + 2] x 3 = ______Solution:a. Perform operations in the innermost set of parentheses.3 + 5 = 8b. Rewriting the equation:[2 8 - 5 + 2] x 3 =c. Perform multiplication prior to addition and subtraction within the brackets.[16 - 5 + 2] x 3 =[11 + 2] x 3 =[13] x 3 =d. Perform multiplication outside the brackets.13 x 3 = 39Rev. 0 Page 17 MA-01
