What does «inverso aditivo» mean in Spanish?
- In mathematics, the additive inverse (also called the opposite or symmetric for addition) of a number n is the number that, when added with n, gives zero. The additive inverse of n is denoted -n. Arithmetically, it can be calculated by multiplying by -1, i.e., -n = -1 × n. The sum of a number and its additive inverse is always zero: x + (-x) = 0.
