Solve: Find the Product of 102×10×10 Using Powers of Ten

According to the order of operations rules, since the exercise has only multiplication, we can solve it from right to left, as this is the simpler exercise:

$10\times10=100$

Now we will get the exercise:

$102\times100=$

Since this is a multiplication exercise where we multiply by 100, without calculation we can simply take the two zeros of the 100 and add them to the result we got in the previous exercise.

It's important to make sure to write the decimal point in the correct place.

Now we will get the number:

$10,200$
