Thanks for help i entered 999 times 5,62*10^14 because in lessons we use ",". But i changed with "." and it said to me correct.

sorry for abbreviation. I'm doing everything and finding the result = 5,62*10^14 or 5,62E+14 and i just want to be sure 1,23 has 3 significant figures right? or should it be 1,234?

Sorry for my bad English but i don't know if i understood true. u mean use "1e = 1.60217646e-19C" in your calculations and express your result after all the calculations finished, right ? Edit : i just changed - to + nothing more :)

I searched from the net it says 1e = 1.60217646e-19C so 1,60 is its 3 digit version and it equals 1,6. I thought that way. And yeah i fixed the -/+ problem but still not true

It says in question "Express your answer using three significant figures." Now; I know 1e = 1,6*10^-19C -90μC=-9*10^-5C N=q/e so (-9*10^-5C)/(1,6*10^-19C) =-5,625E+14 or -5,625*10^14 but that's a computer program so i don't know what it really wants from me i don't know my answer is true or...
