# #RealNumbers

“Now imagine a number?”

“You want an imaginary number?”

“Yes, Imagine it.”

“Okay.”

“No, I’m going to read your mind… hmm… was the number 369.”

“No, the number you gave me is a real number.”

“Yes, but… anyhow. Let me try again… hmm… was it the number 185.”

“No, that one is real too.”

“What does real or imaginary have anything to do with anything? Of course the numbers I give you are real numbers. What number did you pick?”

“10i”

“What?”

“10i. That’s an imaginary number.”

“What’s this ‘i’ thing in it.”

“It’s the square root of -1. That’s what makes it imaginary.”

“That makes no sense. Now, I suppose that you can do 10i + 2, right?”

“Well, yes. That’s a complex number.”

A funny design for math enthusiasts, students, teachers and engineers showing the real numbers -1, 2 thirds, square root of 2, pi and the corresponding teal numbers. For people with a sense of humor who love math and enjoy a pun.

So tonight when I was trying to think of what's required to prove distributivity of #RealNumbers I had to think of how things go wrong. The problem is that you gotta show that the rounding errors with truncation go away when you increase the precision to infinity.
