That's not really true.

You'll regularly see textbooks where 3x/2y is written to mean 3x/(2y) rather than (3x/2)*y because they don't want to format

3x
----
2y

properly because that's a terrible waste of space in many contexts.

That's what I said.

You generally don't see algebra in grade school textbooks, though.

12 is a grade. I took algebra in the 7th grade.

Grade school is a US synonym for primary or elementary school; it doesn't seem to be used as a term in England or Australia. Apparently, they're often K-6 or K-8; my elementary school was K-4; some places have a middle school or junior high between grade school and high school.
