1. The problem statement, all variables and given/known data

The electric charge of an electron is -1.6 x 10^-19 C. What is the force exerted between two electrons separated by one meter? Is it attractive or repulsive?

2. Relevant equations

F= K Q1Q2 / D^2

3. The attempt at a solution

Im horrible with large numbers and especially at negative exponents....so this is a guess

K = 9x 10^9 N x m^2/c^2

Q1 = -1.6 x 10^-19 C

Q2 = -1.6 x 10^-19 C

D= 1 m

F= 9 x 10 ^9 N x m^2 X ( -1.6x 10 ^-19 C x -1.6x 10 ^-19 C / 1^2 m)

F= 9 x 10 ^9 N x m X (3.2 x 10^19 C^2 )

F= 28.8 x 10^28 NxmxC^2.....is the answer i got....

I know i am completely off but how can i do this ...this is basically math but im just not with well large numbers...
