This podcast episode addresses a listener's question about the difference between "alphabet" and "number," expanding into a discussion of English expressions using these words. The hosts explore phrases like "alphabetical order," "alphabet soup" (used to describe confusing or nonsensical information), and "the ABCs of something" (referring to the basics). They also discuss "numerical order," "it's a numbers game" (referring to chance and persistence), and "a numbers person" (someone skilled with numbers). A role-play example demonstrates the use of these expressions in a classroom setting. Listeners are encouraged to try using these expressions and to follow the podcast for future episodes.
