What is the math called that expresses for exmple 2 plus eight plus five equal 6 reduced?
There is no kind of math that I am aware of in which 2 + 8 + 5 = 6.
It used to be called 'casting out nines' but more generally is called 'modular arithmetic.' To determine if a number such as 285 is divisible by 3 you add up the digits: 2 + 8 + 5 = 15, then if the answer is more than 9, add them up again: 1 + 5 = 6. If the final answer is 3, 6, or 9, the original number 285 was divisible by 3: 285 = 95 x 3. If the final answer is 9, the number was divisible by 9. So 1287 adds up to 18 and 1 + 8 = 9, so 1287 is divisible by 9. (1287 = 143 x 9.) If the answer is 3, 6, or 9 and the original number was even, it was divisible by 6.
