Hey, my mistake this morning (-25 when it should have been -24) was bad enough. But we skipped from -21 to -10 without anyone mentioning it.

So we should be at -17.

-15.

3i * 5i

(Does that mean "iii * iiiii"?)

...

Silly but serious math digression here: If -15 is 3 * 5 * i^2, or 3 * 5 * i * i, or 3i * 5i, does that becomes i*i*i (3i) * i*i*i*i* (5i), or just (since i^1=1) 1?

... Err ... I used to be a math major. This used to be simple/trivial. What the heck am I doing wrong?

Answer: Drink coffee. 3i = i+i+i, not i*i*i. Silly me.
