  1. We've already seen the number negative i, so presumably we can put different
  2. real coefficients in front of i. 3i for example, is equal to just i plus i plus
  3. i, or 3 i added together. So again imaginary numbers operate in pretty much the
  4. same way as real numbers. Thinking about this, what do you think we get if we
  5. square 3i, apply the same rules that you know worked for real numbers. Real
  6. numbers, and simplify this answer as much as you can.
