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

Question

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

00:00 Multiplication and division come before addition and subtraction, so we'll start with them

00:11 Addition and subtraction are at the same level, so we'll solve from left to right

00:18 And 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:

$25-12=13$

$13+8=21$

$21$
