Re: math question

Hi Sarah;

because 5 x 20 = 100. How do you do long division?

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

Re: math question

Hi Sarah;

Look at the drawing. How many times does 20 go into 1?

Re: math question

Hi;

That is not right. 20 can not go into 1. 20 is bigger than 1. Do you understand  what I am saying?

Re: math question

hi Sarah

If you want to learn how to do division, I suggest you start with what you can do, eg.  take aways.

So instead of 100 over 20 how about

"How many 20s can you take from 100 ?"

See picture.
