PC hardware--CPU & Motherboard & RAM/Adding mA


I you say 20mA you would write it as .020 Amp.

Now if you want to Times .020 by 4 I get .080 if I do it by Hand.

But if I use a Calculator I get .08 why does it not show the last Zero?

What I meen is .020 times 4 = .080 and this is 80mA but when the Calculator says .08 this is not 80mA can you help?

I'm sorry but mathematics is not my expertise. Just because I have built and repaired 100s of computers doesn't mean I know the "math" of what goes inside these components. In many years of experience I have never needed to know the "math". Not trying to sound short. Just sorry I can't help you.
