Subtract $6.57 from $10.00. (I guess without a calculator).
Congratulations! You are capable of managing your own funds according to the government!
I guess because it you're doing it on paper, it'd require carrying numbers? Am I the only one who counts up? i.e. add 3 to get $.60, around $.40 to get to $7 then add $3 for the 10, so you have $3.43?
