## Algebra 1: Common Core (15th Edition)

Because of order of operations, we first consider what is within the parenthesis: ($6^{2}$-$3^{3}$) Once within the parenthesis, we know that we first consider exponents and then subtract. Thus, it follows: ($6^{2}$-$3^{3}$)=36-27=9 We use this back in the initial expression to find: 9$\div$2=9/2 =4.5
