First off, here are some math puns from punoftheday.com:

1. Some mathematicians are reluctant to cosine a loan.

2. I was kicked out of math class for one too many infractions.

3. A mathematician that couldn’t stop adding up recently went incremental.

4. I used to hate maths but then I realised decimals have a point.

5. I didn’t understand the math, so the teacher summed it up for me.
