Unscramble the Blue Letters

I was top of my class, and we were about to start the etisnexon mtahs course. I was really excited about this brand new topic coming up, ceplmox numbers. I like complex. My taecehr was priming us for the concepts with some qutsneios about square roots. Square of nine — three; square of 256 — sixteen. Too easy. Then she asked the trick question: What about the sqraue root of negative one? Of course, we were all over it — "Come on, Miss! We all know you can't take the square root of a negative." "That's true in the real world," she said. "But in the complex world, the square root of negative one is the imaginary number i."

Original Text

I was top of my class, and we were about to start the Extension Maths course. I was really excited about this brand new topic coming up, complex numbers. I like complex. My teacher was priming us for the concepts with some questions about square roots. Square of nine — three; square of 256 — sixteen. Too easy. Then she asked the trick question: What about the square root of negative one? Of course, we were all over it — "Come on, Miss! We all know you can't take the square root of a negative." "That's true in the real world," she said. "But in the complex world, the square root of negative one is the imaginary number i."
