E.g.:
We wish to input the following data: 10/5, 20/8, 20/8, 30/11, 30/11, 30/11, 60
ln2/40ln3, 45/13 (we note 10/5 as the first input thus x
1
=10 and y
1
=5)
• During the data input operation, as long as you have not pressed [DT], use [AC] :
30 [AC]
30 [,] 11
30 [,] 11 [SHIFT][;] [AC]
• If, during data input, you wish to delete the last value entered and for which
you have pressed [DT], use [SHIFT][CL] :
Just after 45 [,] 13 [DT], [SHIFT][CL] deletes the input 45/13.
• To delete a value input beforehand, you must enter the value followed by
[SHIFT][CL] :
10 [,] 5 [SHIFT][CL]
deletes the input 10/5.
20 [,] 8 [;] 2 [SHIFT][CL]
deletes the two data entries having a
value of 20/8.
30 [,] 11 [SHIFT][CL]
deletes one of the three 30/11 entries.
60ln2 [,] 40ln 3 [DT] [SHIFT][CL] deletes the entry from the calculated value.
