Ready to put on your mental arithmetic hats? We’re dissecting an idiom that will have you crunching numbers metaphorically, and that phrase is *do the math*. Don’t worry, though. I promise it’s more about language than algebra!

## Is It Do the Math or Do the Maths?

Since both *math* and *maths* are quick versions of the word *mathematics*, you could use both phrases and still be correct.* **Doin**g math is more common in America, and do math* is more commonly used in British English. The meaning is the same; it’s all about figuring something out, although not necessarily using numbers! (Thank goodness! I’m a word nerd, not a number nerd.)

## Do the Math Idiom Meaning Broken Down

The phrase *do the math* is an idiomatic expression we use to describe putting together the facts of a situation to figure out or understand the truth behind it all. It’s about analyzing a situation, understanding the implications, or deducing something based on the information available.

A great example is my kids. When they have too much tech time, they’re grumpy and short and tend to act out. When I reduce their tech time, they’re far more pleasant, play outside, and work on their hobbies. Which one is better for them? I’d just say, “Do the math!”

## Origin and Etymology Behind Do the Math

It’s derived from the literal action of doing mathematical calculations to solve a problem and move forward.
