Re: [math-fun] More 4th grade "math"

I bought a whole pad of 8.5" X 11" sheets of "division tables" that include the various quotients of low integers when each is divided by 0. Including the correct value of 0/0 -- something I'd always wanted to know! --Dan On 2014-02-04, at 10:22 AM, Bill Gosper wrote:

Anyway, ("drill and kill") Saxon Math is apparently using "factor" to mean divisor, presumably because it has fewer syllables:

"Write the factors of 10 that are also factors of 15."

Sounds like they are expecting a "factor" of 1. (I should've checked if they think 1 is a prime.)

In the same assignment,

"Divide 20/9. Write the quotient as a fraction." "Divide and write the quotient as a fraction: 25/6"
