Mathematical connection ratio (in the form of a:b:c), where a, b and c can be negative numbers? For example:-1:2:(-3) and-1:2:3.
In the continuous ratio A: B: C, A, B a:b:c can have negative numbers, and the first term does not need to be positive.

But not all three are negative. If all three are negative numbers, each is multiplied by-1 to become three positive numbers.

Negative items must be enclosed in brackets, such as-1:2:(-3) and-1:2:3, which are not standardized.

It should be (-1):2:(-3) and (-1):2:3.
