Multiplying by 10 When you multiply by 10 you move the number up a place value (you just add a 0 to the number) E.G 10 X 9 = 90 so at first the 9 was in the ones then by adding the zero the nine moves up to the tens. so do you get it now? Dividing by 10 When you divide by 10 its basicly the same as multiplying by 10 but you move it down a place value (you take away a zero) E.G 10 divided by 20 = 2 so at first the 20 was in the tens then when i toke off the 0 it moved to the ones. so do you get it now? in the comments please tell me if you learned something new for this.
