The Whole Numbers are the natural numbers (1, 2,
3, ), and the number zero (0).
3

• When we multiply one (1) by any number, the
  result (product) is the number that one was
  multiplied by, regardless as to whether one was
  multiplied by the original number before it, or
  after it.
• The rule reads
• 1 x a a
• or
• a x 1 a
• So 1 x 5 5 and 8 x 1 8

4

• When we multiply any number by zero (0) , the
  result (product) is zero, regardless as to
  whether the original number was multplied by the
  number before it, or after it.
• The rule reads
• 0 x a 0
• or
• a x 0 0
• So 0 x 7 0 and 9 x 0 0

5

• When we multiply two numbers, the order doesnt
  matter that is, the product (result) is the
  same.
• The rule (of Commutivity for Multiplication)
  states
• a x b b x a
• Just as 4 x 7 28,
• it is also true that 7 x 4 28 .

6

• You may have remembered being asked to memorize
  whole number multiplication facts (your
  multiplication tables) in grade school.
• The next slide is a table of products of whole
  numbers 0 through 12.

• To use this table, simply take any number
• in the top row and follow down that column and
  any number in the first column and follow across
  that row, and their product can be found where
  that column and row intersect.
• Notice that the product
• 6 x 9 54
• can be found by using the above mentioned
• process with the table see next slide

• But we could have started with the 9th column and
  the 6th row, and notice that the same product
  (54) can be found where that column and row
  intersect too!
• This is because of commutivity that is,
• 9 x 6 54 just as 6 x 9 54
• See the next slide

• The next 91 slides will be randomly mixed flash
  cards for multiplying whole numbers 0 through
  12, which drill practice the facts from the
  multiplication table we just reviewed. The
  answers will be revealed (UPSIDE DOWN) two
  seconds after the flash card pops up
• Use the NEXT button (below on the right) to get
  more flash cards.
• If you wish to end the session, use the END
