They are both positive numbers. I want to see if, when subtract, do they
equal a negative number?

I'm not sure which "result" you are refering to, but this echo's if:
$quant is greater than $amount
$amount is less than 0
$quant is less than 0
if ($quant > $amount or $amount < 0 or $quant < 0) {
echo "You don't have that many!";
}
