D’oh… deciding not to devote a mess of time to GIMPing “additive inverse — I can do it later — but YAY for Youtube… John Barclay informs that I can grab number lines by tracing spreadsheet graphs.   Note to self:   This is great for your FSI presentation (“GIMP FOR PEOPLE WHO DON’T HAVE TIME TO […]

So… exponents and variables and … zero power.   It’s a “touch base on this” section in pre-Algebra, nothing huge or convoluted (and I don’t *think* negative powers).
