Unscramble the Blue Letters
I was top of my class, and we were about to start the Extension mtahs course. I was really excited about this brand new topic coming up, complex nrmeubs. I like complex. My teehcar was priming us for the concepts with some questions about square rotos. Square of nine — three; square of 256 — stixeen. 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 wrold, 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."
