Once I Thought Excel Was a Great Tool

I taught Math or something like Computer Literacy to children several times, in several different schools, to different ages.

For several years I thought that Excel was a great tool for doing that.

I mean, isn't it Great?  you put '1' in Square A2 (you need A1 for the title)

then you put =a2+1 in A3. Then you copy all the way down to A41, and there you have the numbers from 1 to 40, right there...

Then you do them multiplied by 10 in column B, Squared in column C, and Cubed (divided by 10) in column D. Then you do a graph...

So much math. All of it done by the students themselves. takes so little time.

And you can also do Pascal's triangle...

No wonder I thought excel was a great tool.

But this little graph you see above?

I made it with Google Documents.

Why?

For starters, I didn't have to pay for the software...
