I am generally good at math but some reason airline points confuse me a lot. Even after readying a bunch of guides online. Could someone explain it better to me?

If a jetblue point is worth 1.3 cents, does that mean that for every point I use, if I were to convert the points to a dollar amount, the points give me an extra .003 cents per every 1 cent I would normally pay in dollars? Would that be correct?

If we take a mint ticket that is worth $598.10 in dollars and 45300 points + 5.60 in taxes/fees how much "dollars" would I be paying if I used points? Would it be 598.1/45300 = ~1.3. So for every point I get .003 cents extra. So 45300*.003=135.9 So If I pay with points and convert to dollars I would be paying 598.10 - 135.90+ 5.6 = 467.8 Is this correct?
