On the TI30X IIB the negative symbol is located one button to the right of the decimal place, just below the number 3.
To enter a negative number press the negative symbol "(-)" whose location was described above and then enter the positive form of the number. You will see the negative symbol on the screen indicating that the number is negative.

### Why can't I multiply negative numbers on my El-520x???

Make sure you use the +/- key (located just to the right of the decimal point key) to enter a negative number, not the - key (to the right of the + key, used to subtract one value from another).

For example, press +/- 4 / +/- 3 = to divide -4 by -3 .

### Negative numbers with even exponents on casio fx-115es

When you push the change sign (-) button, a number button, and any even power it returns a negative value.

In other words if you type -4^2 it will treat it like this:

-(4)^2 = -16

Even though any number to an even exponent should be even. To get around this any time you have an even power on a negative number type it like this.

(-4)^2 = 16

To take the log of a number, enter the number then press the LOG button, then the =.

There's a negative button and a minus button. I think you're accidently pressing the negative button. The actual subtraction button is the red "-" button above the "+" button. I hope this helps, but if all else fails, you can always add a negative!
