Which term describes the collection of basic multiplication problems and answers that people memorize?

• A. Fact family
• B. Product rules
• C. Multiplication facts
• D. Times tables

Answer: (C)

The main idea is knowing the quick, memorized products for simple multiplication problems. This set is called multiplication facts because each fact is something you can recall from memory, like 3 times 4 equals 12 or 7 times 6 equals 42. The term times tables refers to the chart that shows these products, which helps you learn and remember the facts, but the collection itself is specifically called multiplication facts. A fact family groups related facts that use the same numbers and show their relationships, including division, but it isn’t the whole memorized set on its own. Product rules aren’t a standard name for the memorized facts; they describe properties or methods related to multiplication rather than the set of facts to memorize. So, the best term for the collection you memorize is multiplication facts.
