Lots of people have an intuition of what math is, but I haven't had it explained to me properly. Look at a classic:

2 + 2 = 4

Where is the math? The numbers, 2 and 4, are not math. Some people say the = is math, but 4 = 4 is just true, there is nothing being done. Maybe the +, but could just rotate it 45°

2 × 2 = 4

Math is abstract, and therefore cannot be rotated, proving the + is not math. I demand answerd!

That's not well-defined!
