這計數機是在十進制系統中新增了三個數字③=3.333...，⑥=6.666...，⑨=9.999...，看看計算的結果。
關於③和⑥：
十進制系統常用的數字是２和５，要避免使用３，因為常遇到不盡循環。事實是３的用途比５大。若在十進制中增加③和⑥兩個數字，例如發行＄③和＄０.③等貨幣單位，可以免去除以３所出現的麻煩，連除以６也一併解決。
關於⑨：
其實每個整數都有兩個無窮小數表示法，如
３ ＝ ３．０００... ＝ ２．９９９...
如果配合③和⑥，在十進制數字中再增加一個⑨來代表９.９９９...，那麼，⑨和１０的數值相同，⑨是個未進位的１０。人類自古以來是採用立即進位法，９之後是１０，所以缺乏未進位十的符號。未進位的１０有什麼作用？
首先，例如叫做８０年代，是人們看見８０－８９都是８字，就視為同一組。這是對十個一組的誤用，因為這不具十倍數的意義。
其次是電腦學的第０。十個一組，１至１０需要兩位數表示，０至９只需要一位數。所以強行把數字改為以第０開始，把問題解決，也會變得工整對稱（以１開始會不工整）。但是以０來代表第一個數字，這不合常理，也造成混亂。（需然電腦是二進制的，但情況是相同。）
如果最小的單位不立即進位的話，即 ... ８ ９ ⑨ １１ １２ ...，這就消除了對十個一組的誤用，及１０需要兩位數表示的問題，亦合理地以１開始，而且同樣也會工整對稱。

This calculator is adding three digits to normal decimal system.
The new three digits are ③=3.333...，⑥=6.666...，⑨=9.999...。
About ③ and ⑥
Decimal system always avoid to use 3, because it is easy to get unending figure, so use 2 and 5 instead. But in fact, 3 is more useful than 5. If we add ③ and ⑥ to our decimal system, for example, $③note and $0.③coin, it will solve the trouble of divided by three, and also divided by six.
About ⑨
In fact, every integer can express in two circulating decimals, e.g. 3 = 3.000... = 2.999.... To match with ③ and ⑥, if we add one more digit ⑨ to represent 9.999... in decimal system, ⑨ will be an un-carry 10. Human being developed number system with carry at once . What is the usage of un-carry 10?
First. For instance , "eighties" is people find that 80-89 beginning with 8. It is a misunderstanding of "a group of ten". It is not multiple of ten.
Second, zeroth in computing. In group of ten, 1-10 need two digits, but 0-9 only one. So, computing solve the problem by force to begin with 0 not 1. It also become symmetrically. However, to begin with 0 is against the common sense, and make trouble. (The situation is the same with binary system.)
If the smallest unit not carry at once, i.e. ... 8 9 ⑨ 11 12, it will eliminate misuse of group of ten, and problem of 10 with two digits. It is also symmetrically.
