To solve the expression by following the order of operations or PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), we need to simplify inside the parentheses first and then multiply by -1/2.
1) By following the order of operations:
-1/2(8+6) = -1/2(14) = -1/2 * 14 = -7
2) By distributing to remove the parentheses:
-1/2(8+6) = -1/2 * 8 - 1/2 * 6 = -4 - 3 = -7
Therefore, both ways result in the value of -7.
calculate the value of this expression in two ways: by following the order of operations and by distributing to remove the parentheses.
-1/2(8+6)
