What do those two symbols mean? and how to use them

M* = Memory Total

M Diamond = Memory Sub Total

You should also have:

M + = Memory Add

M - = Memory Subtract

Hope this helps.

Please remember to post a rating if I have helped you.

Have a good day.

Mac =)

It can mean many things, depending on context. Perhaps most commonly, it indicates the first derivative.

^!^ is just laugh, not sure what ^!! means (could be spelling mistake --ha ha)

In what context? In the unit conversions it's "inches." In the key markings, if you mean "ln" (lowercase 'ell' not capital 'eye') then it's "natural logarithm."

Do you mean that you stored a number in a letter symbol, and now you want to remove that value?

- Press [2nd][+] to open the (MEM)ory Management tool.
- Press [2:Mem Mgt/]
- Press [1:All]
- Scroll down to find the variable you want reset.
- Gighlight the letter symbol and press the [DEL] key.

The radical symbol is used to calculate square roots. It a radical has a small 3 to the top left of it, it means cubic root. It it has a a small n or a small x to the top left of it, it means nth root.

The way any of these roots works is one of the following:

Enter a number (positive for a square root or an nth root with n even) then press the square root button. The result is then displayed.

The other way is to press the root key then enter the number whose root you wan t calculate. The result is then displayed.

If you press the square root key and a radical is displayed withy a left parenthesis, you can be sure it is the second way.

The "^" symbol stands for exponents. For instance 2^3 = 8.

Sorry, the TI83/83Plus/84/84PLUS/ Silver edition do not have a key or a command to calculate a %, or enter a % symbol. They do not have Greek alphabet letters either.

However in the Finance application there is a TVM variable called tvm_I% but you cannot isolate the % symbol. Similarly, in the TABLE setup you have DeltaTbl variable that fixes the step in a table, but you cannot isolate the Delta symbol.

These are the native capabilities of this family of calculators, and that does not mean that there does not exist a third-party program that can do what you want. You can look on the ticalc.org website.

Just wondering, why would you need these particular symbols when they mean nothing to the calculator?

Hello,

You are not using the correct syntax of the exponential function.

**[SHIFT][e^x] ( number)** .

[SHIFT][e^x] 1 EXE] gives 2.718281828

[SHIFT][e^x] [(-)] 3 gives 0.04978706837 . The (-) is the change sign to the left of the [EXE] key.

For simple arguments the parentheses are not necessay, but it is safer to use them to avoid ambiguities and erroneous results.

Hope it helps.

Hello

Mode lineIO ( eye O): means the input is the done the old fashioned way: all the symbols you enter are at the same level; you get no scaffolding in the expression; ambiguity is lifted by using nested parentheses.

The other option MathIO presents the display as in a text book.
