Cool o.o

Though I learend that for Triangle Formula/Rules

it’s just easy way to remmebr the Formula xD

Realy nice

Thnx

27 plus ‘what’ is 60?

Or more specifically, 6 + 8 + 13 + ? = 60

In either case, the missing number is 33.

How did you get the 33 form the 27 and 60?

I learned this from one of my non-sat students years ago. Works great for the SAT though, especially with more complicated average problems (the test writers’ favorite)!

Did you make this ‘pie’ up yourself, or is this actually something that is learned?

Either way, its A shortcut than the conventional equation

In an average pie the bottom two numbers multiply to give the top number. So the 60 comes from 15 times 4. Let me know if you have any other questions!

Where do you get 60 from?
