Use the (-) key just to the right of the decimal point to enter the negative sign. The - key is used to subtract one value from another.

I have a possible glitch on the Sharp EL-531X calculator. If I use the negative (+/-) key BEFORE hitting enter, the number is made negative as it should be. But for whatever reason, AFTER I hit enter, it...


I doubt that it has a glitch. Although possible, it is not very probable. Try to use the calculator correctly.
Follow the algebraic logic.
If you did not input any value the answer memory contains the value 0.
When you press (+/-) followed by [=] it takes the value in answer memory and negates it, thus giving you (-0).
Adopt a consistent way of inputting numbers, namely always enter the negation sign before the number that is negated. The calculator will enclose the negated number between parentheses, which prevents may errors. Too bad this feature has not been kept in more recent calculators by Sharp.

When I square a negative number, my calculator gives me a negative number. i.e. -4^2=-16


No, you're not squaring a negative number, you're negating a square. When you press (-) 4 ^ 2 ENTER , the calculator is calculating -(4^2). 4^2 is 16, and the negative of that is -16. What you want to do is to calculate (-4)^2 by pressing ( (-) 4 ) ^ 2 ENTER .

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!

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 =

How do i input a negative exponent on my ti30x IIs


Use the EE (enter exponent) key (2nd-shift of the key just above the 7) to enter the exponent. Use the (-) key just to the right of the decimal point to enter a negative number.

The - key subtracts one number from another. The (-) key enters a negative number.
