WebAlgebraic properties. Multiplying a number by −1 is equivalent to changing the sign of the number – that is, for any x we have (−1) ⋅ x = −x.This can be proved using the distributive law and the axiom that 1 is the multiplicative identity: . x + (−1) ⋅ x = 1 ⋅ x + (−1) ⋅ x = (1 + (−1)) ⋅ x = 0 ⋅ x = 0.. Here we have used the fact that any number x times 0 equals 0 ...
