Infinity may not be a number...

The square root of -1 is an imaginary unit (it doesn't exist.) Can you please explain how are you adding it to infinity?

If the square root of -1 doesn't exist ( it equals i ) then half the math I took in college also doesn't exist.
No like the reason they.made i is cause the actual square root of -1 didn’t exist, so they could say the square root of negative 25 is just 5i
At least at my grade that’s what I know
At least at my grade that’s what I know
I mean you can’t have a square root of a negative number
Cause any number squared is positive
I pulled this list from https://www.geeksforgeeks.org/how-are-complex-numbers-used-in-real-life/. Of that list I used imaginary numbers for 1, 2, 3, 4, and 6 in college. Not that I remember much of it now. That was over forty years ago.
"Complex numbers are used in many varieties of fields in real life. Below given are the most important uses of complex numbers, and their proper explanation is also explained.
1. Complex number is used in Electronics.
2. Complex number is used in Electromagnetism.
3. Complex number is used to simplify the unknown roots if roots are not real for quadratic equations.
4. Complex numbers are used in computer science engineering.
5. Complex number is used in mechanical and civil engineering.
6. Complex numbers are used in control systems."
“Complex number is used to simplify the unknown roots if roots are NOT REAL for quadratic equations.”
Root of -1 is defined as I
Which is used to simplify other negative roots

Nope.
Complex Numbers "don't exist." They cannot exist, we cant even IMAGINE such a thing.
As was drawn out for us, by brother brilliance right below me.
Because i the imaginary unit does not exist.
Nothing but trolls are almost always the ones that answer my posts, 1st.
But Infinity+i [i being the square root of -1] is "really" a complex number, however!
