I'd like to think again how a fluorescent lightbulb tube works...

If I use a few radio signals to make a lightshow in it, doesn't it
work that the pattern of light depends on the radio signals? but then
maybe a few at a time?
so the radio signals together make a pattern like what matters for
both of the radio signals, then doesn't it work out that there's a way
to forumlate the signals
to make a pattern in different ways?

then isn't this what can do math computation? If it's figured what
signals find what response in the flurescent lightbulb tube, then
can't I find signals that say a math operation and a lightshow that
says a math answer?
