think of it as an algorithm and its pretty easy
I love him. He's like those happy old people who become known for sitting by the side of a busy street and waving to passing cars. People drive by regularly and beep just to see him and get him to wave to them.

That's just like our Arpi... except he doesn't wave or anything. He just says mean things to you.

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

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.
