Question about Texas Instruments TI-85 Calculator

Negative answer when squaring a neg number

My TI-85 must be in some sort of mode that allows it to do this: when I square a negative number, I get a negative answer. I also get a negative answer with any exponent (including all even exponents). Please help, I want it to properly show me positive answers to a negative number to an even exponent. Thanks!

    It seems the calculator needs to have the negative number in parentheses before applying the even power.

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 =

I cant figure out how to get the square root of a negative number


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.

When i square a negative, i get a negative answer, how do i fix it so it gives me the positive number?


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.

When I square a negative number (eg -2^2) it gives me a negative answer (-4) why isn't it giving me a positive answer?


You're not squaring a negative number, you're negating a square. What you need to do is calculate (-2)^2 instead of the -(2^2) you're now calculating.

How do you use the imaginary number with the TI-84 calculator?


If you want the answer in rectangular form, set MODE a+bi and tap ENTER and QUIT. Tap square root sign, tap (-)4 and close the parenthesis and tap ENTER. The answer is shown as 2i.
If you want the answer in polar form, set MODE to re^xi and and DEGREE. Tap ENTER and QUIT. Tap the square root sign, tap (-)4, close the parenthesis, and tap ENTER. The answer shown is 2e^90i. (2 at ninety degrees). If you selected RADIAN mode, the answer would be 2e^1.57i (2 at 1.57 radians; or 2 at pi/2 radians)

TI-83 Plus No Longer Squares Correctly


when you type -2 imagine your calculator doing the equation: -1 x 2. The - sign actually stands for a -1 so when you do -2 squared your calculator is simply following order of operations. It first squares the 2 making it 4, then it multiplies the negative making it -4. In order to get around this you must use parenthese. (-2)^2.

Hope this helped

Wrong answer with squared negatives.


Your calculator will square a number before it applies the negative sign, so what you're actually doing is squaring 2, then applying the - sign to your answer. You need to put the -2 in parenthesis, so (-2)^2. That will give you 4. Hope this helps!

The calculator cannot do that natively. There may be a program that you can drop onto your calculator to do it though.

has a ton of stuff... I saw two programs that sounded like it would do what you wanted... but I don't have an 85 to test it on so sorry if they don't...

Ones I saw are "alghelp.zip" and "algef85.zip"
