-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.
(72 x 1) (36 x 2) (24 x 3) (18 x 4) (12 x 6) (9 x 8)
(6 Cosx)2
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.

1 x 12 2 x 6 3 x 4
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.
yes they do . if you mutiply 6 by 7,and then divide by 82,multiply by 12.1415923454
