I had an idea, but I wanted to make sure it didn't run afoul of the word count.

It's something like this. You have equations on a chalkboard.

How many words would this count as?

There's a case for an equals sign being a word, or a minus/plus sign or a number e.g. x^2 is 2 words and not one.

Here are the examples.

Would line 2 and 3 be 5, or 3? (a^2 and b^2 could be 1 word or 2.)

x=2ab

y=a^2-b^2

z=a^2+b^2

I may be chiseling here but I'd like to know how much extra fun stuff I could fit in. Of course if there is any doubt I will assume these take the maximum number of words. One image or line doesn't mean much of course but there may be multiple so they could really add up.

Thanks!
