You’re probably thinking what the hek does that even mean? Multiples of 9, if separated, can be used to make the number 9.

For example, 9×3 = 27. If you separate 27 to give 2 and 7, adding the 2 and 7 together gives 9.

This is true for the first 10 multiples of 9.

1×9 = 9 0+9 = 9

2×9 = 18 1+8 = 9

3×9 = 27 2+7 = 9

4×9 = 36 3+6 = 9

5×9 = 45 4+5 = 9

6×9 = 54 5+4 = 9

7×9 = 63 6+3 = 9

8×9 = 72 7+2 = 9

9×9 = 81 8+1 = 9

10×9 = 90 9+0 = 9

There you go. Hopefully you understand what I was getting at now!

It is also a very useful way to check if you’re answer for calculations with the number 9 are correct, that is if it is within the first 10 multiples.

You now have permission to go ahead and amaze everyone with this fact.
