abc common stock paid 1.32 pesos in dividends last year and expected to grow 7% annually. Compute for the value of the stock with expected rate of return 11%.

Rather than pressing the = key, press the "Sto" key to assign a value to a letter. eg. "12 [Sto] n ".

So expected returns are just a little more advanced version of probability - without getting too in detail it uses weighted averages so you do not have to add the same number 17 times.
Let's first define our variables:
E(X) = Expected Return X1 = Variable 1 P1 = Probability 1 (in decimal format so 55% would be .55) X2 = Variable 2 P2 = Probability 2 (P2 is also equal to 1 - P1)
So the expected return formula is as follows:
E(X) = (X1)*(P1) + (X2)*(P2)
Plugging in our given numbers we get E(X) = Expected Return X1 = 300,000 P1 = 10% or .1 X2 = 40,000 P2 = 1 - P1 = 1 - .1 = .9
E(X) = (300,000)*(.1) + (40,000)*(.9) E(X) = 66,000
Now remember this does not include the opportunity cost of spending your four years in college studying biology instead of another degree.

This calculator is incapable of displaying simplified fractions (i.e. 1 ½), you will have to use the decimal value or contain your complex fraction in parenthesis. (i.e. (5/2).)

Use the y^x key, located just above the 9 key. For example, to calculate 2 to the 6th, press
2 y^x 6 =

Make sure you press the ENTER key after each data entry, before pressing the down-arrow key.

If this doesn't solve the problem, could you reply to this post giving the exact key strokes you're using?

2nd [FORMAT] 6 ENTER 2nd [QUIT].

Press 2nd [FORMAT]. Press 0-8 for the number of digits after the decimal point, or 9 for floating-decimal, followed by ENTER. Press 2nd [QUIT] to exit.

Press 2nd [FORMAT] 4 ENTER 2nd [QUIT].

To calculate the natural logarithm of the value in the display, just press the LN button. If you need the common (base-10) logarithm, compute it as ln(x)/ln(10). That is, divide the natural logarithm of the value divided by the natural logarithm of ten.

Press 2nd [P/Y] down-arrow to see the current C/Y (compounding periods per year) value. Enter the desired value, press ENTER, then press 2nd [QUIT].

( . 2 9 * . 3 9 ) + ( . 5 5 * . 2 2 ) + ( . 1 6 * . 2 +/- ) =

In AOS mode you can skip the parentheses.

You have your payments-per-year set to 1 and the calculator is showing an annual payment of $5000. Press 2nd [P/Y] 1 2 ENTER 2nd [QUIT] to change it to twelve (monthly). Now pressing CPT PMT should give you a monthly payment of $536.82.

Set the number of payments per year to 1. Press 2nd [P/Y] 1 ENTER 2nd [QUIT].

It's the key marked "I/Y" (for interest per year), located second from the left on the third row from the top.

There isn't one.

Sorry if that wasn't the answer you wanted to see, but there it is.

That depends on the interest rate.

2nd [CLR TVM] (clear previous data)
5 0 0 0 PMT (monthly payment)
2 0 2nd [*P/Y] N (20 years of monthly payments)
annual interest rate I/Y (annual interest rate)
CPT PV (compute present value)

At 10% it's about $518,000
