"I" stands for an imaginary number

I asked my teachers and they said they don't teach it because they believe that check books and taxes are something your parents should be teaching you at home. My schools didn't have drivers Ed either.

We learned it in mide school as well. We were all encouraged to open bank accounts and start saving money too.

I use them every single day and if we hadn't invented them my work would be ten times harder. They are used to transform trigonometry into algebra, which is something you always want. Electromagnetism without complex numbers is pure torture.

The electromagnetism we did in physics did not deal anything with imaginary numbers.

You can represent a propagating plane wave with a cosine, but as soon as you want to take into account things like absorption you need exponentials. When working with complex numbers, everything is exponential, no more cosine. Many concepts merge into one elegant framework. My thesis has a chapter on the subject if you're curious :D.

While I am curious, I am also on break lol. But it does sound interesting. We didn't do much in absorption with electromagnetic spectrum. We did reflection and refraction but nothing else.
