The minus is always centered while the negative is always at the top.

If you're in algebraic mode, press 1 - 2

You should see the centered minus sign between the one and the two. Now press ENTER, and you should see the top negative preceding a one.

The two are two different things. The first indicates subtracting one number from another. The second indicates a negative quantity.

Are you sure the minus is at the top? Or was the negative centered?

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 ^).

If opposite means that you want to rotate the image or picture for projector mount in the ceiling.

KEYS location: (keys are located back side of the projector there is 2 keys 1 for menu and second is a joystick witch have 4 arrow keys and center press is a enter key)

Press MENU button to display the menu screen.

then use joystick UP and DOWN to select the OPTION menu. Press joystick for ENTER to display the option screen. Then press joystick UP and DOWN to select INSTALLATION.

Then press joystick RIGHT and LEFT to select your required image rotation there is four type of rotations.

1. FRONT DESK

2.FRONT CEILING

3.REAR DESK (A translucent screen is required for rear projection)

4.REAR CEILING (A translucent screen is required for rear projection)

If opposite means negative to positive so there is no any setting in your projector witch is chang your picture or image positive to negative.

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).

You're not calculating the square of a negative number, you're calculating the negative of a square. You need to use parenthesis to indicate the square of a negative number.

You're calculating -(3^2), not (-3)^2.

To calculate the latter: ( (-) 3 ) x^2 =

Actually, you're negating a square, not squaring a negative. When you put in -x^2, it's getting calculated as -(x^2). In order to square a negative number, use parentheses and calculate it as (-x)^2.

Also, make sure you're using the +- key to the right of th decimal point instead of the - key when entering the negative number.

Use the log function (common logarithm). See screen capture for markings
on key.

To evaluate the negative of a logarithm

Enter the number (argument) of the logarithm

Press the = key to have it calculated.

While result is still displayed, press the sign change key or (+/-).

Beware that -log(number) is not necessarily a negative value.

Another way to calculate -log is to use the relation

log(1/a)=-log(a) .

Your example

3 [EXP] [(] [+/-] 2 [) ] [LOG][=] [+/-]

[EXP] is the key to enter exponent of a power of 10 :It is a shortcut, so no 10 is entered. Respect the key sequence above.

[ (] left parenthesis to prevent ambiguity due to the negaticve exponent. Just a security.

[)] is the enclosing right parenthesis

[+/-] is the Sign Change key

The key to use for the square, and the cube are well marked and they share the same physical key (X to 2) or [SHIFT][X to 2]. Similarly the keys to use for the square root and the cube root share the same physical location (the square root key, to the right of the square key).

For any other exponent, including fractions and negative exponents you use the universal power key labeled [X to ] ( X with a raised square).

For any other exponent, including fractions and negative exponents you use the universal power key labeled [X to ] ( X with a raised square).

- You enter the base (the number to be raised to a power).
- You press the [X to ] power key.
- You close the parenthesis (the right one).
- You press [=]

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.
