Question about Texas Instruments TI-30XA Calculator

1 Answer

Incorrect multiplication i have an old ti-30xa, in the drawer for years. tried to use it & it seemed to be giving incorrect answers. tested 9 x 4 & it calcs 16. changing DEG to RAD doesn't make any difference here-- i think it's a different setting that's causing the error.

I dont understand why I keep getting the wrong exponet in trying to figure out 1500nm divided by 10^9. the answer I get is 1.5 *10^-7 -but the answer is 1.5*10^-6. What am I doing wrong?


Without knowing exactly what you're doing I can't be sure, but I suspect you're entering the 10^9 as something like 1 0 EE 9 .

1 0 EE 9 gives you 10 * 10^9, which is 10^10. You should be doing this as 1 5 0 0 / 1 EE 9 = .

Any sin, cos, or tan function problem always gives the incorrect answer. I can use my TI 55 that is 30 years old and get the correct answer, but my son's TI84 plus silver edition is incapable of giving the...


Make sure you have the proper angular mode set. The TI-84 can work with degrees or radians.

Press MODE to bring up the mode screen. Use the arrow keys to highlight either "Radian" or "Degree" on the third line and press ENTER. Press 2ND [QUIT] to exit the mode screen.

If this doesn't do it, please reply to this post giving an example of a calculation and the answer you're getting from the calculator.

HOW DO I USE THESE SYMBOLS ()


Use them to group expressions, to override the precedence of operations. For example, if you put in
  1 + 3 * 2 + 2  
the calculator will give you 9, which is 1+(3*2)+2, because multiplication takes precedence over addition. If you put in ( 1 + 3 ) * ( 2 + 2) then you'll get 16 because you've overridden the precedence to do the additions first.

Simplifying fractions on the TI-30XA


Two ways:

1) hit the equal sign

2) hit 2nd and [d/c] (you can do this multiple times to see it as the most reduced improper fraction or as a mixed fraction)

Inputing Scientific Numbers


If you mean using the "EE" key it's straightforward.

To enter scientific numbers, enter the number, then press EE, then the exponent value. The TI-30XA will stay in scientific display until you "clear" or turn it off. It will also switch to scientific notation if you multiply big numbers that exceed the display.

E.g. Input 3, EE, 10, X, 3, EE, 10, =, gives you the answer 9 times 10 to the power 20. Press the "square root" key and you will get back 3 times 10 to the power 10.

You can mix entries too, e.g. 3, EE, 10, X, 2, =, gives you 6 times 10 the power 10....
