For an example:

15x10^-4J + 4.82x10^-4J / 8.5 x 10^-6C

When I add the numerator, I'm thinking 20 x 10^-4

Then, 20 x 10^-4 / 8.5 x 10^-6......which I'm thinking 20 x 10^-4 / 10 x 10^-6.

This gives me 200.....but, since I made the denomenator a bit larger in the previous step, I'll enlarge the answer a bit.......so the final answer is 220.

When you acually do the calculation on a calculator, the answer comes out to be 233.

To what degree do you suggest manual calculation to be accurate to? Please give an example.

Thanks!
