# Math Help - constant times a constant = ?

1. ## constant times a constant = ?

if i were to multiple a constant by a constant, would it just be a constant?

for example:

y = c1(c1e-x)
y'= -c1e-x

edit: i guess i should square it since it's the same constant.

2. ## Re: constant times a constant = ?

Yes, square it. You may give the constant another value, e.g.: $c_2:=-c_1^2$.
