QuestionEvaluate the expression using order of operations: $-7 + (-6) \cdot 8 =$ (simplify your answer).

Studdy Solution

STEP 1

Assumptions1. We are given the expression $-7+(-6) \cdot8$ . We need to use the order of operations to simplify this expression. The order of operations is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). This is often remembered by the acronym PEMAS.

STEP 2

First, we need to perform the multiplication operation in the expression. According to the order of operations, multiplication is performed before addition.
$-7 + (-6 \cdot8)$

STEP 3

Now, plug in the given values and perform the multiplication operation.
$-7 + (-6 \cdot8) = -7 + (-48)$

STEP 4

Next, we perform the addition operation.
$-7 + (-48)$

STEP 5

Perform the addition operation to find the final value of the expression.
$-7 + (-48) = -55$ The value of the expression $-7+(-) \cdot8$ is $-55$ .
