What does the EE stand for on a scientific calculator?

I need to know what each E in EE stands for.

Hi, Jarrod.

is used to enter scientific notation. See this answer in our archives:

EE Key on a Calculator
http://mathforum.org/library/drmath/view/54346.html

If you go there and read it, you will see what one of our Math
Doctors understands to be the meaning of the E's, namely "Engineering
Exponent." I don't know for sure that he is right, and in fact I don't
find his phrase used anywhere else on the Web, but it makes some
sense.

I searched a little more using Google (just looking for the phrase "EE
key") and found this alternative explanation:

Your calculator should have a key for entering scientific
notation. It probably is labeled either EXP or EE (for
"exponent" or "enter exponent") .

So now we have two possible answers. I'm leaning toward the latter,
because it sounds familiar; but if you want to be sure, why not
e-mail someone at Texas Instruments or Hewlett-Packard, which made the
first scientific calculators, and ask what it means to them? (Then
let me know what you find!)

Or you can trust what people say TI says. Here is a page that answers
our question, which I found by adding to my search the phrase "enter
exponent":

Well, back in 1973, when I read my manual for my Texas
Instruments SR-50, they told me it stood for "Enter Exponent".
Since they probably invented the key about then, this has to be
correct, right?
