I’ve been looking at patterns lately. I believe there may be an issue with the “number” feature.

According to the Using Patterns section of the CL documentation, it says that “in Desmos, a ‘number’ is a decimal, a fraction, or a mixed number.” I was looking at screen 14 of the Computation Layer Playground and noticed that it would recognize an integer, a decimal, or a mixed number as a valid input, but not a fraction.

I copied the screen into a new activity and added a note to help check. Here is a copy of that activity:

([Just a Number • Activity Builder by Desmos](https://teacher.desmos.com/activitybuilder/custom/648c87d5c9e19ae14e96ac00))

Is this behaving as expected?

Thanks in advance.
