Solve 25-3×4+4×2: Order of Operations Challenge

Question

Solve the following problem using the order of operations:

$25-3\times4+4\times2=$

00:00 Multiplication and division take precedence over addition and subtraction

00:11 Addition and subtraction are at the same level according to the order of operations hierarchy, so we solve from left to right

00:18 That's the solution!

According to the order of operations, we will first solve the multiplication exercises.

We will put them in parentheses so that we don't get confused later in the solution:

$25-(3\times4)+(4\times2)=$

Let's solve the multiplication exercises:

$3\times4=12$

$4\times2=8$

We get:

$25-12+8=$

Let's solve the exercise from left to right:

$25-12=13$

$13+8=21$

$21$
