% change E = .0022 - (-.0022) = .0044

[(E1 - E0)/E0] * 100% = % change E

[(E1 - E0)/100] * 100% = % change E

E1 - E0 = change E

E1 = change E + E0 = .0044 + 100 = 100.0044

Originally, I got like 100.44. The professor said I was off by a factor of 10, i.e. E1 = 104.4.

Your answer for #1 is already off by a factor of 10.

You calculation for #2 also has another error and it has the wrong sign.

for #3, only % [itex]\Delta[/itex]E was asked. Amazingly enough,
the answer you got was actually correct even tough #1 and #2 were wrong

If you want further help, try to give a more detailed calculation.

Okay. I'm home now. Here's my work.

Refer first post.

You may have to clear the browser.
 
I must be going crazy, because I don't see how I'm calculating #1 and #2 incorrectly!

it didn't help. You link to 2 jpeg files that contain parts of the question
 
Try it again! I renamed them.
 
No one? It's due tomorrow. :-/
