Question about Texas Instruments TI-30XA Calculator

I entered 10

then y to the x

then minus sign

then 9.42

and got .58

Is this correct?

No. You computed 10^1 - 9.42 which is 10 - 9.42 = .58

Instead of the minus key, which subtracts one number from another, use the change-sign key [+<>-].

[1] [0] [y^x] [9] [.] [4] [2] [+<>-] [=]

or else

[9] [.] [4] [2] [+<>-] [2ND] [10^x]

Sorry but you are using the word EQUATION incorrectly. All you have is two numbers you want to divide one by the other.

Enter the numerator 1EE (-) 14, press the division key / then enter the 5 EE (-) 12. Press the = sign.

Note: to enter the negative sign in the exponents, use the change sign key marked**(-), (+/-) or [+/-] **. Do not use the regular MINUS sign.

When you use the EE key, you must not enter the 10. It is understood because EE is a shortcut for***10^**.

What are you trying to do?

Could it be that you entered a + sign followed by a - (minus) sign instead of a change sign (-). +-10

I have done the calculation using the the shortcut key [x10^X] to enter the exponent,and I got the correct result.

I also did the calculation by explicitly typing the 10^10 factor and I obtained the correct result.

The syntax error may come from your using the minus - sign for subtraction rather that the change sign key (-)

Hello,

The calculator has two minus signs

Examples. Let (-) be the negation and -- the regular minus.

You can enter it exactly as it is written above. In this case, you must use the change sign (-) in both factors.

You can also decide to use the power rules and enter the expression as X^( -2 --1/3). In this case the first minus is the negation and the second is the regular minus.

I could go on with a few more examples, but that will take us away from your present concern.

In short.

Do not forget to rate the solution

The calculator has two minus signs

- The regular MINUS sign which is used with the subtraction operation. This operation is binary, requiring two operands (two terms). In a-b, a and be are the operands (they very specific names, but I will skip this detail).
- The negation or change sign. This operation is called unary, requiring one operand. -a means take the negative of the number a.

Examples. Let (-) be the negation and -- the regular minus.

- If you enter (-) 12 the TI84Plus accepts it and calculates the negative of 12.
- If you enter 12 (-) 13 the TI protests with a syntax error
- If you enter 12 ( (-) 13) the calculator interprets it as 12* (-13) and calculates -156.
- If you enter --12, the calculator displays Ans--12, where Ans is the last result calculated. If Ans happens to be 0, the new result is obviously the one you are expecting. But if Ans holds a non zero value, this is incorrect.

You can enter it exactly as it is written above. In this case, you must use the change sign (-) in both factors.

You can also decide to use the power rules and enter the expression as X^( -2 --1/3). In this case the first minus is the negation and the second is the regular minus.

I could go on with a few more examples, but that will take us away from your present concern.

In short.

- If the minus sign is the leftmost (first) symbol in your function (after the Y1=) you should use the negation. Any subsequent minus should be the regular minus --
- If the minus sign is the first symbol in an exponent, you must use the negation. Any subsequent minus in the expression of an exponent should be the regular minus --

Hello Michelle,

Sorry, the answer was posted as a clarification request. Here it is again.

1. Use the key that appears on the sixth line in the picture. 10 [Y to the x] [(+/-)] 14 : the (+/-) is the change sign/ negation sign, not the regular minus sign. This key can be used to calculate the power with any exponent ( negative, positive, integer, fraction, decimal, ..) 2. The procedure above is not efficient since the calculator has a short cut to 10 to the power., the key labeled [EE}. With this key you enter 1.[EE] (+/-) 14

Hope it helps.

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.

Its a little strange. Suppose you want subtract 10 from 38. Do this:

Enter 38 press plus key.

Enter 10, press minus key.

Press the equal sign. You will have the result.

Enter 38 press plus key.

Enter 10, press minus key.

Press the equal sign. You will have the result.

Hello,

To use the exponential function,**you must enter the number then press [2nd][e to the x] or [e^x] for short.**

e^(-0.1) is entered as (-)0.1 [2nd][e^x], where**(-)** is the change sign key

You will need to use extra parentheses to avoid errors.

**20 - 18*( (-)0.1 [2nd][e^x] ) [=]**

The Minus sign between 20 and 18 is the regular one. The** (-) **before the 0.1 is the change sign key **(-)** or sometimes labeled** +/-**. The asterisk is the multiplication sign.

Hope it helps.

I'm assuming you want the +/- symbol like you see in the quadratic formula. There is no key to enter this. You will have to enter 2 separate problems. Enter the numbers with the + symbol and then enter the numbers with the - symbol.
