Question about Texas Instruments TI-84 Plus Calculator

Ad

The E is an engineering notation for 'x10^' so the answer there 4E-7 = 4 x 10^ -7 (I'm using the x as multiplication). I'm afraid there isn't a way of changing it (that I know of) but it is not difficult to learn, it's just a simple way of writing scientific notation!

There is no such thing as a TI89 Plus Silver Edition.

If you mean the TI-89 or TI-89 Titanium, press diamond / (the diamond key below the 2ND key, then the divide key).

If you mean the TI-83 Plus Silver Edition or the TI-84 Plus Silver Edition, press MATH left-arrow 4 .

There are no such buttons, You'll find the lcm (least common multiple) and gcd (greatest common divisor) functions in the MATH NUM menu. Press MATH, right-arrow, and select the desired function.

There isn't one. If you want to convert a value from decimal to fraction, use the >Frac function (press MATH 1). If you want to enter a fraction, simply enter the numerator, divide, then the denominator.

For example, to calculate 1/4 + 1/3, press

( 1 / 4 ) + ( 1 / 3 ) MATH 1 ENTER

and you'll see 7/12.

Enter the fraction for example: enter 8/12.

The answer will be .666666

Then click Math (which is located under the Alpha button).

Click the ->Frac button (the first one).

It should come up as Ans->Frac.

Click Enter.

It should now read 2/3 which is 8/12 reduced.

Note: I have a TI-84 Plus Silver Edition, and the TI-84 Plus might not have this function, but that is how I do it on my TI-84 Plus Silver Edition
