Good morning!

I have never been good with math. So, of course I opt to seek a degree in computer programming!

So, I have a few equations that I am trying to figure out:

Compute the following expressions:

e1 = 1 + 2 + 3 + 4 + 5 + ... + 123

e2 = 1 + 3 + 5 + 7 + 9 + ... + 123

e3 = 1*2*3*4*5* ... *33

e4 = 1*1 + 2*2 + 3*3 + 4*4 + ... 100*100

e5 = 2 to the 18th power

How would you do these in Algebra? Thanks in advance.
