Evalute the expression:
Evalute the expression:
Follow the correct order of operations: parentheses, exponents, multiplication, division, addition, subtraction. (This is typically abbreviated as PEMDAS. Note that both multiplication and division, and addition and subtraction, are equal to each other in terms of rank, so when both are present, solving the equation proceeds from left to right).
First, simplify anything in parentheses.
Next, simplify any terms with exponents.
Now, perform multiplication.
Since all we are left with is addition and subtraction, we perform simplification from left to right.
Thus, our answer is:
