It means the calculator is current set to the degrees mode. Trigonometric function depend on how you measure the angle. The most common units are degrees, radians, and grads. To change the mode on the 30Xa, press the DRG key to cycle through them.

Do you mean x^2 (x-squared)? That's to the left of the "7" key.

The change-sign key is marked "(-)" and is to the right of the decimal point key.

If you mean the key to raise a number to an exponent, it's the key marked "y^x", two keys above the "7" key. If you mean the key to enter an exponent of ten, it's the key marked "Exp", just above the "7" key.

You need to select the number of decimal places you would like, or if you would like the calculator to behave as normal. Press SET UP and select FSE (press 1) . You now have 5 options.

0: FIX means you can choose a fixed number of decimal places for every calculation.

1: SCI means scientific notation and choose the number of significant values you would like to deal with.

2: ENG means engineering and the power goes up in multiples of 3.

3: NORM1 and 4: NORM2 are the usual or normal settings on the calculator. Most school calculations will use NORM1 mode.

I have done the calculation using the the shortcut key [x10^X] to enter the exponent,and I got the correct result.

I also did the calculation by explicitly typing the 10^10 factor and I obtained the correct result.

The syntax error may come from your using the minus - sign for subtraction rather that the change sign key (-)

Two keys can be used to enter negative exponents on the TI-30Xa scientific
calculator; the [y^x] key or the [EE] key. The [y^x] key is used for
all exponents while the [EE] key is used for scientific notation only.

The examples below will demonstrate how to use both keys:

1) Entering 7^-2.

• Press [7] [y^x] [2] [+/-] [=].

• The calculator will display: 0.20408163.

2) 1*10^-3.

• Press [1] [EE] [3] [+/-] [=].

• The calculator will display: 0.001

If it shows up on the display, it means the calculator is standing by for input of a variable name to recall the variable's value. If you mean the key, that's the key used to recall a variable from memory.

For square roots, use the square root key just to the left of the divide key. For example, 4 square-root = will give you 2.

The calculator doesn't have any way to store equations, scientific or otherwise. If you mean scientific notation, use the EE key just above the 7 key to enter exponents. For example, to enter 1.23x10^6, press 1 . 2 3 EE 6. For negative exponents, make sure to use the +- key to the right of the decimal point instead of the - key.

If you mean using the "EE" key it's straightforward.

To enter scientific numbers, enter the number, then press EE, then the exponent value. The TI-30XA will stay in scientific display until you "clear" or turn it off. It will also switch to scientific notation if you multiply big numbers that exceed the display.

E.g. Input 3, EE, 10, X, 3, EE, 10, =, gives you the answer 9 times 10 to the power 20. Press the "square root" key and you will get back 3 times 10 to the power 10.

You can mix entries too, e.g. 3, EE, 10, X, 2, =, gives you 6 times 10 the power 10....
