I’ve been trying to figure out how to provide student feedback if three cells are multiplied to result in the correct product (Since there is more than one answer)

Example: Multiplying Exponents • Activity Builder by Desmos

I need to leave here in a sec or I’d make a sample for you. You’ll need to use `numericValue`

or `simpleFunction`

to determine the correct value to compare. You can insert student cell values into your calculations by referencing them wrapped in `${ }`

.

I don’t think patterns would be too helpful here. I’d create `simpleFunction`

’s of the student product and target product, then compare a number of evaluations of each.

Thanks so much. Originally I messed up the simplefunction by not putting the a,b and c like you did:

productF = simpleFunction(expProd,`a`

,`b`

,`c`

)

So if there were 4 variables in the product expression (eg 12abcd), I just would add a `d`

to the line above?

Correct. You need to specify all variables used in your simpleFunction. If you do not, the default is “x”.
