Maths

Today for math, I did this very unusual math question...
1. Pick a amount less than $10. I picked  $8.39
2. Reverse the amount. $9.38
3.Take-away them together. $9.38-$8.39=0.99 ( 99 cents )
4. Reverse the amount you got on step 3. $9.90
5. Add step 3 & 4 answer's together then you will get $10.89

Try other amounts - you will still $10.89! ( Really, I tried another one )

0 turned 1/4 clockwise = 1/

l = 1 for the denominator 

n  without the edge and a bit bigger = 10

Also, there was hundred, i forgot what it was though
