Homework Help: 7th grade, math

Posted by Sharron on Thursday, October 21, 2010 at 7:24pm.

Can someone explain the steps to solve this problem?
If a number ends in zeros, the zeros are called terminal zeros. For example, 520000 has four terminal zeros, but 502,000 has just three terminal zeros. Let N equal the product of all natural numbers from 1 through 20: N=1x2x3x4x...x20.
How many terminal zeros will N have when it is written in standard form?

Thanks!
