Solve Step-by-Step: 2+4×5÷2+3 Using Order of Operations

Question

$2+4\times5:2+3=$

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

00:11 Multiplication and division are at the same level, so we solve them from left to right

00:27 We're left with only addition and subtraction

00:29 Addition and subtraction are at the same level, so we solve from left to right

00:34 And that's the solution!

According to the order of operations rules, we first insert the multiplication and division exercises into parentheses:

$2+(4\times5:2)+3=$

Now let's solve the expression in parentheses from left to right:

$4\times5=20$

$20:2=10$

And we get the expression:

$2+10+3=$

Let's solve the expression from left to right:

$2+10=12$

$12+3=15$
