my brain is tired i think.what is triangle maths?how does it work

[SKA]

It mats with 3 number you pair them up have to add or minus them from each other and then write the anwser took - sorry I dont think I explained it very well though have a look at it and you'll figure it out!!

[encee]

still can't work it out.what is the logic?

[Cakeboy]

Basically, you add the numbers on the top line together and then put the sum of those numbers into the second line and do whatever the calculation is for the answer:

Eg. 2 + 8 - 3
O+O
A

With this one you would do 2+8 and mentally put that number into the left circle and then do 8-3 and put that number in the right circle.

The sum you're left with then is 10 + 5 so 15 is the answer.

Hope that helps
