HP35s minus sign display is incorrect


The minus is always centered while the negative is always at the top.

If you're in algebraic mode, press 1 - 2
You should see the centered minus sign between the one and the two. Now press ENTER, and you should see the top negative preceding a one.

The two are two different things. The first indicates subtracting one number from another. The second indicates a negative quantity.

Are you sure the minus is at the top? Or was the negative centered?

How do I do exponents on this calculator?


Two keys can be used to enter negative exponents on the TI-30Xa scientific calculator; the [y^x] key or the [EE] key. The [y^x] key is used for all exponents while the [EE] key is used for scientific notation only.
The examples below will demonstrate how to use both keys:

1) Entering 7^-2.

• Press [7] [y^x] [2] [+/-] [=].
• The calculator will display: 0.20408163.
2) 1*10^-3.

• Press [1] [EE] [3] [+/-] [=].
• The calculator will display: 0.001

Depending on your version of the TI-30, you will either find a button with a y to the exponent of x or a button that is the carot (^) sign. you would type (1.0075)^(-240), where ^ is the appropriate button (y^x or just ^).

How would type in scientific notation?


Use the EE key (just above the 7 key) to enter an exponent. For a negative exponent, use the +- key (just to the right of the decimal point key) to enter the negative sign.

For example, to enter 1.2 x 10^-21, press 1 . 2 EE +- 2 1

To switch the display mode to scientific notation, press 2nd [SCI] (the 5 key).

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 =

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.

Negative log


Use the log function (common logarithm). See screen capture for markings on key.
83c0b62.jpg
To evaluate the negative of a logarithm
Enter the number (argument) of the logarithm
Press the = key to have it calculated.
While result is still displayed, press the sign change key or (+/-).

Beware that -log(number) is not necessarily a negative value.

Another way to calculate -log is to use the relation
log(1/a)=-log(a) .

Your example

3 [EXP] [(] [+/-] 2 [) ] [LOG][=] [+/-]

[EXP] is the key to enter exponent of a power of 10 :It is a shortcut, so no 10 is entered. Respect the key sequence above.
[ (] left parenthesis to prevent ambiguity due to the negaticve exponent. Just a security.
[)] is the enclosing right parenthesis
[+/-] is the Sign Change key

How to use the exponent key on a casio fx 300ES calculator ?


The key to use for the square, and the cube are well marked and they share the same physical key (X to 2) or [SHIFT][X to 2]. Similarly the keys to use for the square root and the cube root share the same physical location (the square root key, to the right of the square key).

For any other exponent, including fractions and negative exponents you use the universal power key labeled [X to ] ( X with a raised square).
  1. You enter the base (the number to be raised to a power).
  2. You press the [X to ] power key.
  3. You close the parenthesis (the right one).
  4. You press [=]
Sometimes the result may not be displayed as a decimal number, but as a radical (if you take a root). To make sure it is displayed as a decimal number, in step 4 above, press [SHIFT][=]

1.19x10-4=?


You can download the guidebook for this calculator from TI here.

From page 16:
To enter a number in scientific notation:
1) Enter up to 10 digits for the base (mantissa). If negative, press the +/- key. (The key has two curvy arrows between the + and - but I can't do that on my keyboard.)
2) Press the EE key.
3) Enter a 1 or 2-digit exponent. If negative, press +/- either before or after entering exponent.

They give the example 1.2345 +/- EE +/- 65 which would display -1.2345 -65.
