Question

why digit 9 known as magic digit.

Answer 1

Hi friend!!

So, I think everyone knew table 9

9×1=9

9×2=18

9×3=27

9×4=36

9×5=45

9×6=54

9×7=63

9×8=72

9×9=81

9×10=90

In this table the digit goes on increasing while the other digit decreases as we move from top to bottom.

I think that's the reason digit 9 is called magic digit.

I hope this will help you ;)

Answer 2

HEY DEAR....
HERE'S YOUR ANSWER⬇
I believe you know Multiplication table if number 9. It goes like :
9*1=09
9*2=18
9*3=27
9*4=36
9*5=45
9*6=54
9*7=63
9*8=72
9*9=81
9*10=90

So do you notice that the digits come in an order that is, in the answers, the first numbers (tens place) are in the order 0,1,2,3,4,5,6,7,8,9.
And those numbers in the ones place are in the order 9,8,7,6,5,4,3,2,1. So this is the first reason.

The second reason is that the first five Answers till 45 are then they switch places i.e, Those which were in ones place get switch to the tens place and it continues.
I don't know how to explain it better.
I HOPE YOU FIND IT HELPFUL.
