Use the (-) key for negative numbers (not just exponents) instead of the - key. The - is to subtract one value from another, (-) is to input a negative value.

Look for a key that is marked EE, or Exp, or x10^x. To enter a number in
scientific notation, you enter the decimal part, then press the Enter
Exponent key, followed by the exponent. If exponent is negative, you
precede it with a press of the change sign key (-).

Once a number is entered there is no special treatment: multiply it divide, or add it.

The equivalent od the EE or EXP button on the Casio Fx-115ES is marked as x10^X. It is located at the bottom right of the key pad left of the = key.

To enter the power of 10 in a number written in scientific notation, you press the x10^X button followed by the exponent. If the exponent is negative you press the change sign key first [(-)] , then the one or 2 digits in the exponent.

Example Enter the mass of the proton m_p in kilograms

**1.6726217 [x10^X] [(-)]27 [=]**

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

Depending on your version of the TI-30, you will either find a button with a y to the exponent of x or a button that is the carot (^) sign. you would type (1.0075)^(-240), where ^ is the appropriate button (y^x or just ^).

Use the EE key (just above the 7 key) to enter an exponent. For a negative exponent, use the +- key (just to the right of the decimal point key) to enter the negative sign.

For example, to enter 1.2 x 10^-21, press 1 . 2 EE +- 2 1

To switch the display mode to scientific notation, press 2nd [SCI] (the 5 key).

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.

Scientific notation is a number format that has the following structure (d stands for digit)

one digit decimal mark several other digits [times] 10 raised to power of exponent

d [decimal mark] dddddd...[x] 10^ (-) dd

Here are two examples the last two results. The number of digits after the decimal mark is select by the user depending on the number of significant digits in the data. The exponent can be positive or negative.

In you case, to enter x10^ you press the [EE] key (no 10 is entered) the sign of the exponent and the value of exponent.

d [decimal mark] dddddd...[x] 10^ (-) dd

Use the EE (Enter Exponent) key just above the "7" key. For example, to enter 3.1x10^4, press 3 . 1 E 4.

For negative exponents, make sure to use the +<>- key just to the right of the decimal point instead of the - key.

For negative exponents, make sure to use the +<>- key just to the right of the decimal point instead of the - key.

You can download the guidebook for this calculator from TI here.

From page 16:

To enter a number in scientific notation:

1) Enter up to 10 digits for the base (mantissa). If negative, press the +/- key. (The key has two curvy arrows between the + and - but I can't do that on my keyboard.)

2) Press the EE key.

3) Enter a 1 or 2-digit exponent. If negative, press +/- either before or after entering exponent.

They give the example 1.2345 +/- EE +/- 65 which would display -1.2345 -65.
