You may sometimes find mathematical curiosities.
Here’s a nice operation that a friend told me about:
45 + 45 = 45
I will prove it:
45 is equal to 1+2+3+4+5+6+7+8+9
Thus:
1 2 3 4 5 6 7 8 9
+ 1 2 3 4 5 6 7 8 9
———————-
= 2 4 6 9 1 3 5 7 8
 
246913578 is an anagram of 1 2 3 4 5 6 7 8 9, whose the total is 45
