Best/easy way for invert a float

Sure that would work as well, multiplying by -1 and subtracting from 0 will only change the ± value, so either way should work just fine. Not sure which is the better, less resource-hungry, or “proper” way, but you can do almost anything in multiple ways, so long as it doesn’t affect performance it is just whichever you feel comfortable with.

I believe “0 - X” can be used in Math Expression nodes, while unary operations (in case the prefix notation -1) can not.
