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

Question

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

00:08 Remember, multiplication and division come before addition and subtraction.

00:19 If you only have multiplication and division, solve them in order, from left to right.

00:35 Now, we only have addition and subtraction left.

00:39 These have the same priority, so solve them from left to right too.

00:44 And there you have it! 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:

$2+10=12$

$12+3=15$
