SOURCE: TI-83 Plus No Longer Squares Correctly

when you type -2 imagine your calculator doing the equation: -1 x 2. The - sign actually stands for a -1 so when you do -2 squared your calculator is simply following order of operations. It first squares the 2 making it 4, then it multiplies the negative making it -4. In order to get around this you must use parenthese. (-2)^2.

Hope this helped

SOURCE: I want to do subtraction. But when I enter the "

There's a negative button and a minus button. I think you're accidently pressing the negative button. The actual subtraction button is the red "-" button above the "+" button. I hope this helps, but if all else fails, you can always add a negative!

I have a possible glitch on the Sharp EL-531X calculator. If I use the negative (+/-) key BEFORE hitting enter, the number is made negative as it should be. But for whatever reason, AFTER I hit enter, it...


I doubt that it has a glitch. Although possible, it is not very probable. Try to use the calculator correctly.
Follow the algebraic logic.
If you did not input any value the answer memory contains the value 0.
When you press (+/-) followed by [=] it takes the value in answer memory and negates it, thus giving you (-0).
Adopt a consistent way of inputting numbers, namely always enter the negation sign before the number that is negated. The calculator will enclose the negated number between parentheses, which prevents may errors. Too bad this feature has not been kept in more recent calculators by Sharp.

2 things how do you disable clerk sign on and how do you program a cash/amount tender key it wont give the amount of change


You can't normally turn off the clerk system as it would facilitate terrible fraud. You are just supposed to sign on and start using it.
All cash registers should be able to calculate change. Press SUBTOTAL once you have entered the items. Now type the amount received from the customer (no decimal point). now press Cash (or other payment key) and the change should be displayed.

How to Calculate IRR?


To calculate IRR and NPVEnter the cash flows as follows, remembering the sign convention:
  • Clear previous data by pressing fXY and fCLX.
  • Enter the cash flow at time zero using # gPV [# CF0].
  • Enter subsequent cash flows using # gPMT [# CFj].
  • If a cash flow is repeated, enter the number of times it is repeated (including the first time you just entered) using # gFV [# Nj]. For example, three equal flows in a row would be entered as3 Nj.
  • When you have entered your last cash flow:
    • If you are calculating an NPV, enter your interest rate as # i (consistent with interval between cash flows) followed by fPV [NPV].

    • If you are calculating an IRR, enter fFV [IRR].
This is an excerpt from http://luna.pepperdine.edu/faculty/mkinsman/calculators/hp12c.html
I did not come up with this solution. Just found it for you.

Negative log


Use the log function (common logarithm). See screen capture for markings on key.
83c0b62.jpg
To evaluate the negative of a logarithm
Enter the number (argument) of the logarithm
Press the = key to have it calculated.
While result is still displayed, press the sign change key or (+/-).

Beware that -log(number) is not necessarily a negative value.

Another way to calculate -log is to use the relation
log(1/a)=-log(a) .

Your example

3 [EXP] [(] [+/-] 2 [) ] [LOG][=] [+/-]

[EXP] is the key to enter exponent of a power of 10 :It is a shortcut, so no 10 is entered. Respect the key sequence above.
[ (] left parenthesis to prevent ambiguity due to the negaticve exponent. Just a security.
[)] is the enclosing right parenthesis
[+/-] is the Sign Change key
