The new magic stops working after three days and every spell uses proprietary runes.

and his words struck me deeply because i had already softened the story that had earned this verdict, wrapped cotton around the reality of my fists and slashed all the swear words out of the script before telling my family about the theater and the boy and the darkness from earlier that day

"I-- he wasn't allowed to do that," i stuttered.

and my father said that he just had sympathy is all. one red-blooded american male to another. that i could have said yes. could have given the boy a chance.

the next time i told my family a story at the dinner table, i'd learned my lesson.

"i hit him," i said. i saw my father's face contort out of the corner of my eye. my heart raced. i smiled through my trembling chin. "he kept doing it. so i hit him again."

"that makes you a bully."

this label fit me better. "only to people who bully me first."

"you can't--"

"i think he deserved it," my brother said and fist bumped me over the bowl of mashed potatoes

"me too," my sister said. she watched my dad with interest, learning her own lessons. "im glad you hit him."

"you can always tell a teacher," my step-mom said, diffusing. she offered my dad more wine. "that should be the first step."

"you're going to kill someone one day," my dad said.

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
