Hello

I am brushing up on my basic scientific calculator skills.

I am using the TI 84 plus ce calculator.

There's a key that appears not to be on my calculator.

Looking like a dot symbol.

A beginning of a quadratic equation.

1 Sto Alpha ·

Can someone show me where I can find and how I can place the dot symbol as in the example above.

Are either of these the dot you were referring to?


They can be found by entering the catalog ([2nd] + [0]), then scrolling up.


Most strange symbols can be found in the catalog. Hopefully this helps

I think the instructions you're referencing are talking about the period / decimal point key. [ALPHA][.] is a colon.

Thank you for 2 quick and insightful responses.

On the first reply.

After finding the dot I am looking for and selecting it under the catalog tab.

On the calculator keyboard is there a keyboard combination to type the dot to appear on the calculator screen.

Not besides selecting it from some menu. [2ND][Y=][LEFT][4] is a slightly shorter sequence (while within the program editor).

I think what would be most helpful is seeing the quadratic equation you’re referencing. It’s possible a dot was used to show a multiplication symbol, but I don’t know for sure unless I see the exact equation you’re looking at.

hello TIny_Hacker

I am pressing the 2nd key and the 0 button on the keyboard.

Scrolling down then up.

Under catalog I scroll up to the curly brazes.

Press the enter key.

I don't see a menu for a dot.

Just another curly braze.

Or if I hit enter more then one time I see syntax error.

If you please have any input help is appreciated.

But I think I have interjected all I can.

When you press [2nd]>[0] you're put into the catalog list. It's just one massive list you can scroll through. Keep pressing the up arrow and you'll scroll past the curly braces.

We haven't explained what this dot actually does. It's not used for mathematical operations, it's a style of dot strictly used when graphing. That's probably why it's throwing a syntax error when you try to use it.

Often times people will use a dot to represent the multiplication symbol since they're lazy and it's faster to write (I do it too ). Try doing the formula again, but this time use the multiplication button instead of a dot. The multiplication button looks like an x and is three buttons above [enter].

What instructions are you following?

hello

Thanks all for the consideration and the valuable information.

You showed me how to pick out a special character.

In this case how to insert a dot symbol.

The scientific calculator is certainly a mase of unending.............

Thanks again.
