Reverse a numbers oder

Hello guys,
what node would generate the inverse of a number. I want a texture
to move in the oppsite direction on the x axis of two given quads simulataneously.

I need 0 to be 5 converted to 0 to -5, along those lines

thanks in adavance

Its cool I found it “reverse” node

reverse changes the order of a spread but doesnt inverse numbers…

to inverse a number just use the *** (Value)** node and multiplicate with -1.

you may also find Map (Value) and MapRange (Value) useful

@dave thats right, but once i heard - (Value) with zero minus your number gives the same with better performance

or subtract (Value) … zero minus your number
