Order Property Of Multiplication

In order property of multiplication, the order is not important. That means if we change the place of a number the answer will remain the same.



According to the
1st diagram , there are four groups each group contains three dots. So it will be
4 x 3 = 12


According to the
2nd diagram , there are three groups each group contains four dots. So it will be
3 x 4 = 12


From the above we can conclude that , if you change the place of a number in multiplication the answer remains the same. That means the order doesn’t matter.

What is the answer of ?

2 x 4


So easy !

2 x 4 = 8


Now we will see, if the numbers are switched.

4 x 2 = 8


Oh ! its same as above.

So we conclude that :
2 x 4 = 4 x 2

Fill in the blanks :

1) 3 x 4 = ----- x 3
2) 8 x 0 = 0 x ----
3) 12 x ----- = 12 x 11
4) 23 x ------ = 23 x 32
5) ---- x 67 = 67 x 72
6) ---- x 90 = 90 x 12
7) 12 x ---- = 12 x 89
8) 17 x ---- = 17 x 0
9) ---- x 8 = 8 x 7
10) ---- x 19 = 19 x 20

In which of the following order-property of multiplication is true.

1) 12 x 13 = 13 x 12
2)18 x 8 = 11 x 16
3) 10 x 0 = 0 x 10
4) 9 x 1 = 1 x 9
5) 8 x 10 = 13 x 8
6) 11 x 2 = 2 x 12
7) 3 x 1 = 1 x 3
8)14 x 6 = 6 x 14
9)10 x 3 = 3 x 10
10) 1 x 2 = 2 x 1
