hi can someone make this sound like I didn't copy-paste this answer um I changed some things but it still needs some changes... A complex number is a number that can be shown in the form of a + bi, where a and b are real numbers, and i is a symbol called the imaginary unit.

A complex number is a number that can be shown in the form of a + bi, where a and b are real numbers, and i is a symbol called the imaginary unit.

A complex number is a special number that can be shown in the shape of a + bi. A and B are supposedly real number like 1 and 2. I is a unit instead of being a real number, it's called an imaginary unit, or the imaginary unit.

(Ahem not my best but it's what I came up with)
