It is not necessary: some people find it easier to do so, others do not.
take out zeros
Move the decimal point 3 places to the RIGHT and annex 2 zeros.
The product may not have any zeros if there are "carries" from a product at a lower level.
You annex zeros to get the answer. Such as 0.03 equals 0.030, and you keep annexing zeros to the end to get your answer. Until you get to the hundred thousandths place.
3500-- so 2 zeros

3500-- so 2 zeros
one thing that you can do is divide the 8 into 3, but you will need to annex zeros
Why will there 2 zeroes in the the product of 60X90
The product is 18,720 which has one zero in it
