But strong arithmetic fundamentals are absolutely necessary for strong algebra. I've watched kids struggle with basic algebra because when they don't instantly recognize that 7x8=56, they also don't recognize that 7zx8z=56z(edit: squared).

Edit: thanks to the reply; HN ate my superscript 2. Apparently it doesn't like the unicode multiplication x, either: × ² ?

Hmm. Alright, I can see solid arithmetic being good for introducing the concept of a variable...

...but the only time I ever saw significant numbers when actually doing math was in toy problems that deliberately chose weird, big coefficients, where the arithmetic part was by far the least significant.

Good point ... however, 7z*8z=56z^2.
