You’re in degree mode when you want to be in radians.

If you enter a negative number using the subtract key, it will always give you a syntax error.
There is a difference between the subtract key and the negative key.
The negative 2 is entered with the negative key in the lower right (under the 3).
The subtract 7 is entered with the normal subtract key.
You can get bit the same way if you enter negative numbers in any of the solvers using the subtract key instead of the correct one.

My calculator gives the wrong answer. When I square a negative number, it gives me a negative answer. For example, if I square -2, it says that the answer is -4, even though the correct answer is 4. Is there a way to fix that?
Rana - crwdns2934203:0crwdne2934203:0
Yes. Put the negative number in parenthesis, then square that quantity. The order of operations prioritizes the exponent (over the minus sign), and does the square part first….then adds the minus sign later/after. You have to surround the negative number and sign in parenthesis to tell the calculator to square the negative number. (And yes, it’s kind of annoying.)

i input sin1 and i get .01745… changing from degrees or radians does not change the issue of outputting the same number

To reset as well, press 2nd + clear + on button. If I leave mine out on the desk without covering it or turning it over to keep the panel from seeing anything for whatever reason, the calculator with turn on then turn itself off and it won’t turn back on until I reset it like this and it clears the memory which is annoying to change my mode settings back every time. So I generally try to remember to set it down face down or cover it.

My calculator is stuck on a screen that shows the last calculation I did and a line under it that goes straight across with a long decimal number under that. None of my buttons are working and the software reset didn't do anything either. I've tried waiting out a little to see if it at least turns off but so far there's nothing. Any ideas?

When I try to do integrals I get "fnInt(" on the screen, but all the videos I've watched on it show an actual integral that you fill out. Is it malfunctioning?
