@PettisChristy@aranglancy More wondering: Why was "-3" not originally illustrated as just three anchors in this S's work? V interesting to have +2 & -5 to begin with
@PettisChristy@aranglancy Ah! I see now! They really did just take away anchors! Interesting. Wondering how they knew to have the 2 floats to begin with #elemmathchat
@aranglancy Possibly the same, if S thinks they can only take away as many anchors/floats as they have & have to "add the opposite" when they run out
@aranglancy Sarah, here! A4: I see -3 -(-5) as "took away 5 anchors" -- take away the existing 3 and add 2 floats to make up for the rest #elemmathchat
