Question

To find 6x5, how does knowing 5x6= 30 help you?3rd grade student

Answer 1

This is a multiplication principles.

the rule of multiplication principle is just like a counting principle.

so when we want to find 6 x5 , we simply want to know what is the final number when we add 6 five times .

lets do the calculations :

6 x5 is the same as : 6 +6 +6+6+6 = 30

similarly 5 x6 is the same as 5+5+5+5+5+5 = 30

• The above shows us that it does not matter whether we say 6X5 or 5x6, the results will always be the same, which is in this case 30.
