Solve 15×2×9: Three-Factor Multiplication Problem

According to the order of operations rules, since the exercise has only multiplication, we will solve it from left to right:

$15\times2=30$

Now we will get the exercise:

$30\times9=$

We will calculate the exercise by putting aside the tens of the number 30 and solve the exercise:

$3\times9=27$

Now we can add the tens that we previously set aside, and add them to the result we got.

This way we will get the number:

$270$
