Question about Texas Instruments TI-84 Plus Calculator

Simply convert the fraction to a decimal equivelant. say 1/4 is .250, take your fraction - for example - 3/32 - divide 32 into 3 to get a equivelant decimal.

Set the Real/Complex mode to COMPLEX. (rectangular coordinates). See the screen captures that follow.

For such a sophisticated calculator (computer) a simple thing like entering a fraction seems too difficult to explain. There are a great number of scientific calculators that handle fractions easily.

Anyway, to manipulate fraction without their being calculated numerically, you must use the CAS.

Press MODE then F3 CAS.

In the CAS screen, move cursor to the _numeric option. If it is cheked, uncheck it by pressing F3:Check.

Press OK to exit the CAS configuration screen. Press OK again to exit the MODE screen.

You can know enter fractions using the division key (Z)

If you type 1/5 + 13/7 you will see 72/35

Now if you enter 1/5 then press the ENTER key you will see 1/5. But if you add to that 13/7 you will see 1/5+13/7 and the result will not be calculated. To calculate the resulting fraction you must press EVAL (Green Left Shift ANS) ENTER.

As you can see, this is not the most efficient way to handle fractions.

The TI-84 works with real fractions. It will not convert complex numbers to fractions.

You can convert the real and imaginary components to fractions separately. For your example, 1/(1+i) is .5-.5i. Converting .5 and -.5 to fractions, you get 1/2 + (1/2)i.

Decimal to fraction:
Type in your decimal (i.e. .5)
Then press [MATH] > press [ENTER] on [>FRAC]
Then press [ENTER] again
Example:
.5>Frac
1/2
For a fraction to decimal:
Simply type in the fraction and press [ENTER]
Example:
1/3
.33333333333
(*Note that the decimal value is truncated to fit the screen)

Hope that helps! Have fun calculating!

This calculator is incapable of displaying simplified fractions (i.e. 1 ½), you will have to use the decimal value or contain your complex fraction in parenthesis. (i.e. (5/2).)

The TI-84 doesn't really work with fractions. Type in a fraction as a quotient. For example, to type in one-half, type ( 1 / 2 ).

just type it in, e.g. 1/2 or 3/5.
if you want to have answers display as fractions, press [MATH] ENTER.

A fraction is just division of the numerator by the denominator. So all you have to do is enter the division symbol in place of the fraction bar. If you are trying to enter a mixed fraction: for example 3 3/5 enter: (3+3/5) were the / is the division button or your calculator.

use the "carrot" button, ^. Type in 4^.5 and you get 2. If you are going to use fractions, use the division bar and parenthesis and not the fraction key. Example 4^(1/2) = 2

type the whole number then hit the ABC button then type the numerator then hit ABC then type the denominator

1ABC1ABC2 + 1ABC1ABC2=3

1ABC1ABC2 + 1ABC1ABC2=3
