what is m=c5-47*56

What does this mean?

c5

i mean 5c

it's still just an equation.

m = 5c - 2632
I guess if you want to solve for c, that would be

c = (m+2632)/5

The expression you provided is "m = c5 - 47 * 56". It seems to be an algebraic expression where certain values are being subtracted from the product of 47 and 56. However, I assume there might be a typo in the expression, as "c5" doesn't seem to have any clear meaning. If you can provide the correct expression or more information, I'd be happy to help you further.
