ONE WAY TO DO IT:
14-1%261%2F2=13%262%2F2-1%261%2F2=12%5E1%2F2
writing 14 as 14=13%2B1=13%2B2%2F2=13%262%2F2
and subtracting

It is what you would do if you had $14 and had to pay $1%261%2F2 with exact change.
You would ask for change for $1, and get two $1%2F2 ($0.50) coins in its place.
You would have $13 in bills that you would use to pay the $1 part of $1%261%2F2 ,
keeping the other $13-$1=$12 in bills,
and you would use 1 of the 2 $1%2F2 coins to pay the rest of the $1%261%2F2 ,
keeping the other $1%2F2 coin
That would leave $12 in bills and $1%2F2 in coin in your wallet.
