Please consider revising the stem to replace “the numbers 1-9” with either “the integers 1-9” or “the digits 1-9”. Although I expect that was the author’s intended number set, as written it is ambiguous.
Thank you!

I love these activities. I just put this one into Desmos Activity builder to use it as a warm up.
