Question

What type of number is 2i-7?

Answer 1

Hey there! :)

The number 2i-7 is an imaginary number.

i represents an imaginary value, so therefore, it is imaginary and is considered a speculative number.

Often it represents a value that mathematical rules wouldn't allow, it wouldn't be able to be calculated.

I hope this helps!
