How do you multiply traditionally?
One visualization of multilication is to consider (say 7 x 35) as a grid of dots, 7 dots wide and 35 dots high. Then count up the number of dots in that rectangle. Perhaps simpler is to multiply 7 x (30 +5) = 7 x 30 + 7 x 5; = 210 + 35 = 245.
What does a scatter plot look like?
Ignoring the dots(.) as background, it can look something like: |..............................x...... |.........................x........... |...............................x..... |...........................x......... |..............x...................... |....................x................ |.............x....................... |.....x............................... |...................x................. --------------------------

What is four to the power of four?
