Cách sử dụng
"Do the math" is a phrase that means to use your brain to figure out a problem or situation. It is usually used when someone is trying to show an obvious solution to a problem, or to prove that something doesn't add up. For example, if someone says they can buy a car for $100, you might say "do the math" to show that it's too good to be true. Basically, it means to think about the facts and numbers in a situation to come up with a solution or conclusion.
