It's only a series of multiplications; order and brackets don't matter; like (* is now multiplication sign...no longer x): 2 * 3 * 4 * 5 = 120 2 * 5 * 4 * 3 = 120 2 * (5 * 4) * 3 = 120 Somebody playing a joke on you? Btw, do you understand that your expression can be simplified to: K * e^(gt) Last edited by Denis; May 16th, 2015 at 08:35 PM.
