QuestionCalculate: $3 \times 20 + [45 - (3 + 2)]$

Studdy Solution

STEP 1

Assumptions1. The problem follows 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 need to solve the operation inside the parentheses.
$45 - ( +2)$

STEP 3

Perform the addition inside the parentheses.
$45 -5$

STEP 4

Now, subtract the result from45.
$45 - =40$

STEP 5

Now, we replace the operation inside the parentheses in the original problem with the result we just calculated.
$3 \times20 +40$

STEP 6

Next, we perform the multiplication operation.
$3 \times20 =60$

STEP 7

Replace the multiplication operation in the problem with the result we just calculated.
$60 +40$

STEP 8

Finally, perform the addition operation.
$60 +40 =100$ The solution to the problem is100.
