qwR then select Disp which is4 on the fx82AU PLUS II or 5 on the fx100AU PLUS, then

Answers to fraction calculations are improper fractions
There are several ways to deal with this problem. You can set the calculator to always display answers as
a mixed numeral (see the following instructions) or you can make use of the N function which is the
second function on the n button to toggle between mixed numerals and improper fractions. The n
button will display the value as a decimal.
The calculator is set in the MthIO mode but the fractions show in the old way
You are working in the statistics menu rather than the computation menu. Press w1.
The calculator gives the wrong answer for calculations involving trigonometry
Most likely the calculator is set to radians or gradients and the input is intended to be degrees. See
instructions on page 3 for setting the calculator to degrees.
In statistics the calculator is pasting the value of the mean in place of a score in the data list
You haven't pressed AC to indicate that you have finished entering the scores. The calculator is treating
the mean as a score.
