Re: Middle School Mathematics

Hi ganesh;


In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

Re: Middle School Mathematics

Hi iamfriendly;

Just take and put your answers between the hide commands. I have done one of yours so you can see. Now just edit your post and you will see what I have done.
