-2 x 3
3 is 1 third of nine. so for 1x9 just do 1x3 and times the answer by 3. 1x3=3 and 3x3=9 so 1x9=9. 2x3=6 and 6x3=18 so 9x2=18 and so on and so on.

1 x 36, 2 x 18, 3 x 12, 4 x 9, 6 x 6.
-2 x 3
you can use 6*5 is equivalent to 30. 6*4 is 24 add those and you get 54. REMEMBER you must keep one number whole for this to work.
3 is 1 third of nine. so for 1x9 just do 1x3 and times the answer by 3. 1x3=3 and 3x3=9 so 1x9=9. 2x3=6 and 6x3=18 so 9x2=18 and so on and so on.

To find all the multiplication facts that equal 84, we need to break down 84 into its prime factors. The prime factors of 84 are 2, 2, 3, and 7. Therefore, the multiplication facts that equal 84 are 1 x 84, 2 x 42, 3 x 28, 4 x 21, 6 x 14, and 7 x 12.
2 x 6 = 12 : 3 x 4 = 12 are two facts (or have I misunderstood your use of the word "fact" as in your question?
1 x 36, 2 x 18, 3 x 12, 4 x 9, 6 x 6.
1 x 36, 2 x 18, 3 x 12, 4 x 9, 6 x 6.
You memorize the multiplication facts that 6 times 6 is 36. This tells you that six goes into 39 6 times with 3 left over since 39-36 = 3.
4 and 6, among others.
