Therefore, you can multiply fu by 2, then subtract 1 han, and end up with the same score value. You can also add 1 han, then divide fu by 2, and end up with the same score. This means by memorizing the 30 fu values, you will also memorize the 60 fu values. By memorizing the 25 fu values, you will also memorize the 50 fu values. | Therefore, you can multiply fu by 2, then subtract 1 han, and end up with the same score value.

By proxy, this means that when a hand gains +1 han | By proxy, this means that when a hand gains +1 han (without changing fu), it roughly doubles in point value. Due to rounding, a hand may not ''exactly'' double in value, but it is often very close to double. | ||
==Memorizing common values== | |||
Due to the size of the scoring table, it is important to know the most common values first. Knowing the (1-4 han) + (20, 25, 30, 40) fu hands, as well as mangan+ hands, are the most important. | |||

As mentioned above, adding one han is equivalent to doubling the hand's fu. This rule makes it easier memorize, say, 20 fu, if you already know the 40 fu values. | As mentioned above, adding one han is equivalent to doubling the hand's fu.

Only hands with [[pinfu]] + [[menzen tsumo]] can score 20 fu. Pinfu with ron is worth 30 fu (+10 from closed ron). | Only hands with [[pinfu]] + [[menzen tsumo]] can score 20 fu. Pinfu with ron is worth 30 fu (+10 from closed ron). All other hands cannot reach this amount. | ||
If you know the 40 fu values, you can add 1 han and divide fu by 2 to get the associated 20 fu value. Because pinfu + tsumo is at least 2 han, there is no 1 han 20 fu amount needed to worry about. | |||
