Hi, I'm Charlie Kasov, and this is the difference between trailing zeroes in significant digits. Now, significant digits in trailing zeroes are not that complicated but they're weird. So for example if I measured something and it weighed 3.432 milligrams, and I didn't want to express it as 3.432, I could round it to 3.4 milligrams or I could say 3.400 milligrams. Now these two zeroes are the trailing zeroes. They're obviously not adding value to the number, but they're showing everyone else that I decided I got a three decimal measurement and I wanted to round to one decimal. So, if I took a measurement and weighed 3.52 milligrams, and I expressed it as 3.50 milligrams, there's only one trailing zero in a significant digit, and it is a zero here in the hundredths place to replace the two. So, when I had all the way to the thousandths place, I have two trailing zeroes, when I go to the hundredths place I decided to put one trailing zero. And that's the difference between the trailing zeroes.
