4. Imaginary Numbers are special because:
• When squared, they give a negative result
• Normally this doesn't happen, because: when you
square a positive number you get a positive result,
and
• when you square a negative number you also get a
positive result (because a negative times a negative
gives a positive)

5. • But just imagine there is such a number,
because we are going to need it!
• The "unit" imaginary number (like 1 for Real
Numbers) is i, which is the square root of -1
• A Complex Number is a combination of a Real
Number and an Imaginary Number
• 1+i
• 39 + 3i
• 0.8 - 2.2i
• -2 + πi
• √2 + i/2

6. • Add and express in the form of a complex
number a + b i.
• (2 + 3i) + (-4 + 5i) - (9 - 3i) / 3

7. 2) 24/20i = ?

8. 3) ((2+3i)(4-7i))/((4-7i)(5+4i)) = ?

9. • If ((48-12i)/a)=16-4i then find the value of a

10. • i2012 = ?
