Does anyone have any cool math riddles?

[HedCold]

quickstop, why can't 3 be next to 5? shouldn't it not be next to 2 or 4? can it be next to 2?

[QuickStop]

typo....shit. gotta go edit that post now

[The Sleeper]

how would you do it with exponents?

5*5 - 1^5

yea that's the only possible way of doing it.

[HedCold]

well then for quickstops

whoops nevermind

[HedCold]

[The Sleeper]

[QuickStop]

wrong...no diagnals., youve got 3 touching 4 and 4 touching 5

[QuickStop]

hedcold is right

[Black Lazerus]

oh didn't read the no diangonals part
and hedcold was correct

[The Sleeper]

so what is the best way to figure that one out? besides just randomly putting numbers in?

[HedCold]

1 and 8 were the only numbers with 1 number that couldn't be near them, so it was easiest putting them in the middle. you then fill in accordingly

[HedCold]

this is fun. more more more

[The Sleeper]

yea, i wanna get one too. I feel dumb!

[HedCold]

[HedCold]

whoops i should have shrunk that

anywho here are the rules for it

Try to fill in the missing numbers. Use the numbers 1 through 16 to complete the equations. Each number is only used once. Each row is a math equation. Each column is a math equation.
Remember that multiplication and division are performed before addition and subtraction.
