Common mistake:
Learners sometimes use "arithmetic" when they just mean "math" in general. In modern English, "math" (or "maths" in British English) is the usual word, and "arithmetic" is more specific, meaning the basic number operations. Learners also sometimes say *"an arithmetic"* when talking about the subject, but it is normally uncountable: you say "I study arithmetic", not "I study an arithmetic".
