Question

Solve the exercise:

$2\times3-(4+5):2=$

00:00 Solve

00:03 Always solve parentheses first

00:09 Always solve multiplication and division before addition and subtraction

00:15 And this is the solution to the question

According to the rules of the order of operations, we first solve the exercise within parentheses:

$4+5=9$

Now we obtain the exercise:

$2\times3-9:2=$

We place in parentheses the multiplication and division exercises:

$(2\times3)-(9:2)=$

We solve the exercises within parentheses:

$2\times3=6$

$9:2=4.5$

Now we obtain the exercise:

$6-4.5=1.5$

$1.5$
