### How to show "sqrt(3)" in the Entered column when previewing or submiting answers?

by Jan Hlavacek -Sorry, my actual problem had

```
Parser::Number::NoDecimals();
```

but I forgot to include it in the minimal working example.

That takes care of entering the decimal approximation, but the "Entered" column still shows the approximation.

I would expect that the "Entered" column contains the exact text that the student entered.

by Jan Hlavacek -I think I misunderstood what the "Entered" column means. I expected it to show the exact text that the student entered. It must be available somewhere, because:

The

`Parser::Number::NoDecimals`

checks that it is not a decimalThe Preview column displays the square root, so it knows that a square root was entered.

It seems to me that the Formula flags `reduceConstants`

and `reduceConstantFunctions`

are not applied when parsing student answer, and so the parsed version is reduced. It would be helpful to have similar flags for the student answer, or have another value, e.g. "asis", for the `formatStudentAnswer`

flag, that would use the student's answer verbatim.

### Re: How to show "sqrt(3)" in the Entered column when previewing or submiting answers?

by Jan Hlavacek -I am digging into `AnswerChecker.pm`

, trying to figure out where is the numerical value that appears in the "Entered" column calculated. I am not sure I am unraveling this right, but it seems that `$ans->{student_formula}->TeX`

has the TeX version of the actual entered answer, while `$ans->{student_formula}->string`

seems to have the evaluated numerical version.

Also, in `cmpContextFlags`

, both `reduceConstants`

and `reduceConstantFunctions`

are set to 0, so I am now completely confused.

Is there some way how to disable the "Entered" column on per course basis? I found the `showAttemptAnswers`

flag in `AttemptsTable.pm`

, but I am not sure where to set it and if it is possible to set it for individual courses.

by Jan Hlavacek -Thank you! This does exactly what I need it to do, at least for radicals. I still think students in my remedial class will be confused when they enter something like `2^3`

and WeBWorK will claim that they entered 8, but at least these are actually equal.

### Re: How to show "sqrt(3)" in the Entered column when previewing or submiting answers?

by Davide Cervone -`formatStudentAnswer`

not `formatStudentAnswers`

(singular not plural). If you set that to `'parsed'`

, that should show the unevaluated student answer in the "Entered" column. You don't need to set the `reduceConstants`

or `reduceConstantFunctions`

flags unless you want to affect the correct answer, as these are set automatically during processing of student answers.
