Grace sends this off as a "fuck you" to Stratt and unintentionally eases 40+ years of horrific guilt.

(40+ factoring in the Hail Mary mission, then the time it would take to get back to Erid and the time it would take for the message to get to Earth. Probably closer to 50+ actually).

Original post by @morallygrayautisticscientist here, this post was so funny I decided to draw it lol.

For those of you who joked about Stratt projecting her period cramps on Grace, I drew that too here.

Panel by panel below:

They wear suits, but they don't even know basic etiquette.

This is a given.

If the last digit is divisible by 2 (a.k.a. even), then so is the whole number.

If the sum of the digits is divisible by 3, then so is the whole number. The recursivity of this means that if the sum has multiple digits, you can add them up again until you get a single digit and see if it's 3, 6, or 9.

Like the rule for 2, but check if the last two digits are divisible by 4.

If it ends in 5 or 0.

If the rules for both 2 and 3 apply.

No shortcut. Alas.

Like the rules for 2 and 4, but check if the last three digits are divisible by 8. (Yes, this pattern keeps going for 16, 32, etc.)

Like the rule for 3, but the sum of the digits (or the sum of the sum of the digits, etc.) must be 9.

For example, 294

29 4

4×2=8

29-8=21

21 is divisible by 7

Second example, 1946

194 6

6×2=12

194-12=182

182 is still large, so let do it again

18 2

2×2=4

18-4=14
