i need to transform a stream of data (numbers) i receive from the serial port in numbers that behave in the opposite way.

there, where i have great values (8000) i need 0 and when the great value decrease i need the small one to increase (7999=1)...

i don't know if my explanation is clear enough... i rekon it's called inverse proportionality and i suppose it's easy to do but i'm a stupid with numbers.

hi,

how can i do it with max math?
thank you very much

inverse-proportionality

thank you Brennon
!- 8000 was the stuff i was looking for
it was so simple...;-)
