9 x 7 is 63.
A cheep trick to multiplying numbers by 9 is to hold both hands up. Say your question is what is 5 x 9. Starting with your left hand's pinky and count 5 fingers (thumbs included). Put the 5th finger down. Notice on your left hand you have 4, on your right you have 5. The answer is 45. 5 x 9 = 45.
63/9 = 7
(-9) / (-7) * 7 = 9/7*7 = 9
9 x 6 x 7 = 378
Multiply 7 9 times. Not 7 x 9. Really 7 times 9. ( 7 x 7 x 7 x 7 x 7 x 7 x7 ) which is 40,353,607
9 of them because 9 times 7 = 63
63/9 = 7

9 go into 63 7 times
It is: 9*5*7 = 315
(-9) / (-7) * 7 = 9/7*7 = 9
-9 times 7 equals -63.
The product of 7*8*9 = 504
9 x 6 x 7 = 378
1.2857 times 7 equals 8.9999, which rounds up to 9. To find the answer, all you have to do is divide 9 by 7 on a calculator.
Multiply 7 9 times. Not 7 x 9. Really 7 times 9. ( 7 x 7 x 7 x 7 x 7 x 7 x7 ) which is 40,353,607
1/2 * 7*9 = 31.5
Commutativity (or Abelian) property of multiplication.
