Hello,
Calculators usually have two minuses, the regular minus sign and the change sign sometimes labeled (-) or (+/-). The latter is not meant to effect a subtraction, but to take the negative of the number you just entered. Big difference, would you say, but the syntax is different.
Ex: 15 - 7 is a subtraction with result 8
10 (-) displays -10 on the screen.
In some calculators the change sign is smaller than the regular minus, and is raised above the main line.
Hope it helps.

The plus sign in front of a number does not need to be written. However if the number is negative, the sign must be used. The calculators do have a key to make a number negative. It is usually marked as (-) where the negative sign - is than smaller the minus sign for the subtraction operation. On other calculators, the key is marked as +/-. You must be careful how to use it: it must be the first sign of any expression.

Minus and change-sign are two completely different things. Minus is used to subtract one number from another. When you press minus when the input line is empty, your telling the calculator to subtract. The only way it can subtract the number you're about to put in is to subtract it from something else, and that something else is the previous answer, hence the "Ans."

If you want to input a negative number, use the change-sign key. If you want to subtract one number from another number, use the minus key.

Try pressing the plus key when the input line is empty. You'll get Ans+ in this case as well, The same with multiply and divide, among others, and for the same reason.

How to fix error mesage on TI-30Xa. Every time I press LOG an error sign comes up. how do i fix this?


To take the log of a number, enter the number then press the LOG button, then the =. To take the log of a negative number, enter the negative number using the +/- key just to the right of the decimal point. To calculate the negative of a log, calculate the log and then negate it using +/-. To calculate the antilog (inverse logarithm), press 2nd then LOG.

Bear in mind that LOG is the common (base-10) logarithm. For the natural (base-e) logarithm, use the LN key to its right.

When I punch (-2) to be squared I get a negative number instead of a positive number


You must enclose the negative number between parentheses. (-15)^2 will give 225 because it is the whole content of the parentheses that is squared. However if you write -15^2 the result is -225.Check the key stokes.

I need to use the exponential function with a negative exponent on my TI-30XIIS. I hit 2nd then e^x button, but when i input a negative exponent I get an error. Help please!


I think what you did was use the minus sign instead of the negative sign, on that calculator, the two are not interchangeable. I purposely used the minus sign just now and also got a syntax error, but it looks like it works with the negative sign (-) located under the 3 button.

How do I find the arctan of (-13.9012/-3.20688)? I have tried tan-1 in degrees mode and it is not working. Please help!


I cannot see why it did not work.
Press [SHIFT][TAN] to access the arc-tangent.
The command echoes on screen.
Enter your ratio (why do you keep the negative signs? They cancel one another).
Close the parenthesis and press [=/EXE] key.
In degrees, the angle should be 77.00964571

Note: If you have to enter the negative sign, do not use the subtraction operator, but the change sign key (-).

To the power of a negative


Hello,
Use the small (-) sign sometimes labelled [(-)] or [+/-] and put the whole exponent netween parentheses 18 [y to the x] [(] [(-)] 3 [)] . On some calculators you enter the small - signe after the value of exponent,
18 [y t x] 3 (-) [Enter] should give you 1.7146E-4
In summary the small minus sign; the whole negative exponent between parentheses.
Hope it helps.
