In the first grade I got curious about negative numbers in my calculator. The teacher told me it was a mistake and I shouldn't play with it.

Teacher should have shown you how a number line extends forever in both directions (no reason to think she should have known about imaginary numbers making it extend orthogonally as well)

The teacher probably had no idea what negative numbers were, and if they did, had no training on how to explain that to a six-year-old.

If your teacher was born in the 1800s she would have been right. Negative numbers weren't accepted as "real" for a very long time.
