I do not how to set up the CL for Note 1 and table 4 in Slide 2 so after the students solve 3x^2 -2x-13=0, enter x=(1+2sqrt{10})(3) and x=(1-2sqrt{10})(3) in table4, and hit the submit button , they will receive the “Good work” feedback. If they enter other thing, they will receive the “Please try again” feedback.

I am thinking two things could go wrong in my current setup:

1. I didn’t know the correct command for fraction and square root
2. I think it is said in the CL that whenever table 4 submitted, it will give the “Please try again” no matter what.  
I really have no idea.

I attach my activity below. Can anyone help me with this? Thank you very much.

Try this for the answer variable in the note component.

```auto
answer=
when t.submitted and t.cellContent(1,1) = `x=\frac{1+2\sqrt{10}}{3}` and t.cellContent(2,1) = `x=\frac{1-2\sqrt{10}}{3}` "\n\nGood work! 🤩🤩"
when t.submitted and t.cellContent(2,1) = `x=\frac{1+2\sqrt{10}}{3}` and t.cellContent(1,1) = `x=\frac{1-2\sqrt{10}}{3}` "\n\nGood work! 🤩🤩"
when t.submitted "\nOops. Please try again. :) " 
otherwise ""

```

Since you want a specific format, I just used a latex match. To do this, use the backticks instead of the quotation marks. Also just a helpful tip on the formatting, I just typed in the solution on the Desmos calculator and then copied/pasted it into the code. Works like a charm! 🙂

I am trying to check fractions that repeat decimals and irrational solutions in a math entry box, this code will work when my fraction converts nicely to a decimal, but is not working for thirds or my irrational solutions  
disableEvaluation: true  
check= tan.latex"\frac{4}{3}"  
correct: check  
suffix: when not(this.submitted) “”  
when check “✅”  
otherwise “❌”

how can I change it for thirds and irrational solutions?
