QuestionCalculate the expression: $6 + 5 \times 8 - 7 \times 5$ .

Studdy Solution

STEP 1

Assumptions1. We are given the mathematical expression $6+5 \times8-7 \times5$ . . We need to solve this expression.
3. We follow the order of operations, which 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 perform the multiplication operations. According to the order of operations, multiplication should be performed before addition and subtraction.
$6+5 \times8-7 \times5$

STEP 3

Perform the first multiplication operation.
$5 \times8 =40$ So the expression becomes $6+40-7 \times5$

STEP 4

Perform the second multiplication operation.
$7 \times =35$ So the expression becomes $6+40-35$

STEP 5

Now we perform the addition operation. According to the order of operations, addition should be performed before subtraction.
$+40 =46$ So the expression becomes $46-35$

STEP 6

Finally, we perform the subtraction operation.
$46-35 =11$ So, the solution to the given mathematical expression is11.
