(-3)(-3)? Prove it!

I phrased that wrong.

Examples of money almost always work well. It ‘sticks’ and people accept them.

What I was trying to say is that in this case, while there are abundent examples using money, it just doesn’t seem to ‘stick’ as well. I found temperature over days works better.

YMMV

(-3)(-3)=9 ?

But doesn’t

What happened to the extra dollar?
