Unit complex number

A unit complex number is a type of number that combines a real number and an imaginary number. Imaginary numbers are numbers that cannot be found in the real world, like numbers faster than the speed of light and numbers from outer space. Real numbers are numbers we use every day like 3, 5, 10, etc. A unit complex number combines a real number with an imaginary number and looks like this: a + bi. The real number is "a" and the imaginary number is "bi". Unit complex numbers help us understand math and science questions that involve both real and imaginary numbers.
