It’s a professional hazard, really. Math will do that to you.

They don’t let boring people in.

#### 60. What did the student say about the equation she couldn’t solve? “This is derive-ing me crazy!”

## How to Pick the Best Math Puns

If you are not *that *good at math, it can be hard to choose math puns that are appropriate, funny, *and* relevant to the conversation. But that doesn’t mean you should avoid them altogether! You just need to keep in mind a few simple rules of thumb, and you will always have a great math pun (or two, or maybe even three) up your sleeve — whatever the situation.

**Here is how to pick the best math puns: **

### 1. Consider Your Conversation Partners

Before cracking your favorite math joke, first make sure that your conversation partners will be able to get it. To appreciate your pun, they need to have a certain level of mathematical knowledge. So, young children or arts graduates might not be the best audience for these kinds of jokes.

### 2. Make Sure You Know Your Math

It’s not enough for the people around you to have a decent grasp of math. If you are going to be cracking math jokes, make sure that *you*, too, understand the math behind them! Otherwise, you risk telling the joke wrong or being unable to explain it to other people. In either case, your pun will not have quite the effect you intended it to have.

### 3. Use Math Puns Sparingly

More is less here. A couple of well-timed puns can do wonders and breathe life into any conversation. If you overdo it, however, you will likely bore your audience. Plus, you might come across as a know-it-all, and no one wants that.
