I'm helping my brother who is in grade 9 with his science homework but he forgot his notes at school and I don't remember at all, my future career is not going to involve science so there's no need to remember.

e- could be a representation of the electric charge of an electron (the opposite of that of a proton). It's a tiny awkward number that's a pain to remember/work with, so tends to be treated as a constant until the last part of a calculation.

if it's part of a number eg "433e10" then the e could stand for " multiplied by 10 to the power of". ie a shortcut saving writing out lots of zeros.

It is probably shorthand for ×10^
in other words, 10000 = 1×10⁴ = 1×10^4 = 1e4
0.000001 = 1×10⁻⁶ = 1×10^(–6) = 1e-6
OR it could be the change on an electron.
1 electron charge = 1.602e-19 C
1e = 1.602e-19 C
