Question

すうがくの　じゅぎょうで　なにを　つかいますか。What is this question asking?

Answer 1

It means: "What do you use in math class?"

Breakdown:
- すうがくの (sūgaku no) — "math" (possessive: "of math")
- じゅぎょうで (jugyō de) — "in class"
- なにを (nani o) — "what" (object)
- つかいますか (tsukaimasu ka) — "do (you) use?" (polite)

Subject is omitted, so it asks generally (you/we/people): "What do you use in math class?"

Example answers:
- えんぴつをつかいます。I use a pencil.
- けいさんき（でんたく）をつかいます。I use a calculator.
- きょうかしょとノートをつかいます。I use a textbook and a notebook.
