How can I get a negative number on my TI-30XA calculator? For example, how would I type in:

-6 x (-7)

By the way, the parentheses are not important just tell me how to get the negative numbers please.

- Press the fourth bottom grey key. It has a + and - in it with some arrows right next to a green key.

The same way you type in a negative number. Make sure you use the (-) key just to the right of the decimal point key to enter a negative sign, not the - key you use for subtraction.

Make sure you use the +/- key (just to the right of the decimal point key) to enter the negative number. For example, to divide 2 by -3, press 2 / +/- 3 =

Type the number as a positive, followed by [+-] key (bottom row, left of the [=] key).

I.e. to get -42, key in:

[4] [2] [+-]

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 =

The square root of a negative number is an imaginary number, and the TI-30XA does not deal with imaginary numbers.

However, the square root of -x is equal to i times the square root of x. So, to calculate the square root of -4, for example, press 4 square_root = and read 2. Thus the square root of -4 is 2i.

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.

You compute the negative of a logarithm the same way you compute the negative of anything else. However, do you really mean the antilog (inverse logarithm)? Use 2ND [e^x] for the natural antilog, 2ND [10^x] for the common antilog.

For negative exponents, as well as negative anything, use the (-) key next to the decimal point. For your example, 1 EE (-) 6

You have to use the EE button right next to the parenthesis and the sigma plus button. So 1.7 EE and then your exponenet. If it is a negative exponent you need to hit the negative button before you type in the number.
