It is not necessary: some people find it easier to do so, others do not.
take out zeros
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.
The product may not have any zeros if there are "carries" from a product at a lower level.
3500-- so 2 zeros
Why will there 2 zeroes in the the product of 60X90
Yes
take out zeros
2
There are 3 zeros in the product.

102 zeros.
To determine the number of zeros in the product of 11,000,000 and 10,000, you can add the number of zeros in each factor. The number 11,000,000 has 7 zeros, and 10,000 has 4 zeros. Therefore, the total number of zeros in the product 11,000,000 x 10,000 is 7 + 4 = 11 zeros.
one thing that you can do is divide the 8 into 3, but you will need to annex zeros
3500-- so 2 zeros
Why will there 2 zeroes in the the product of 60X90
The product is 18,720 which has one zero in it
