The Imaginary Number In Mathematics Explained
The Square Root Of -1 Generates An Imaginary Number
In mathematics, the square root of any number, negative or positive, is always supposed to be non-negative. Owing to this, the square root of no real number results in -1. Since this highlights a limitation in mathematics, the concept of imaginary numbers was introduced,where the imaginary unit i equals the square root -1. The inclusion of imaginary numbers allows one to expand the scope of the number system in mathematics by including complex numbers.

They kicked him out after growing frustrated with his inability to follow a stable path.
