i was given a sheet which stated that the charge of an electron is -1.6x10^-19 but after looking it up on the internet it seems wrong (might be a typo in the sheet).
However, one of the questions I found in my homework said (basically):
"a polythene rod is charged by rubbing and is stroked several times across a metal cap used to measure charge. the initial reading was 0. after 3.8s the final reading was -6.4 x10^-8C. calculate the number of electrons transferred."
how can the charge be negative? is it another typo? or is the sheet correct? also would i just divide the charge given by "e"?

The charge of an electron is indeed: -1.6x10^-19.
