Origins? edit
Where does the term come from? The link for reference 1 seems to be not responding at the moment. I think a wikipedia entry on the topic should include something of its origins or who coined the phrase. Tassit (talk) 02:02, 14 June 2019 (UTC)

More formal? edit
The article says that "number sentences are used to introduce students to notions of structure and algebra prior to a more formal treatment of these concepts". Do I understand correctly that
- "3+ ⬜ = 10"
is considered a number sentence, but
- "3+x=10"
is not? And is the former considered less formal than the latter?
