Thanks. I’m not actually part of the Desmos team, just a user who enjoys the coding puzzles and helping people out. First, you can use countNumberUsage to identify specific expressions. (See post 6 in this thread). Second, if you have equivalent expressions, you could just create a function that is the difference of the two. Being equivalent, any value of x should evaluate to zero. Say you want a student to simplify exp1 in a math input. exp1=`4x-2x+5` f= simpleFunction("${exp1} - (${this.la…

Thank you! That helped me get everything working and my kids liked the activity!
