People really like to twist the numbers and digits bringing fun into life. For example, someone asks, “how much is *two* and * two?*” : the answer should be *four* according to basic (decimal based) arithmetic. But the same with base *three* (in ternary number system)* *equals to 11. *Two and Two *also equals to *Twenty Two.* Similarly there are many ways you can add them and get different results.

**Dmitri A.** **Borgmann, **the German recreationalist, puzzler and father of *logology*, noticed the following expression

11+2-1=12

which is valid in following four ways:

**Usual Decimal Summation:**

11+2=13 & 13-1=12 $ \Rightarrow$ 11+2-1=12.**As Roman Numerals:**

XI + II = XIII & XIII – I = XII $ \Rightarrow$ XI+II-I=XII.**As set of Characters:**

11 added 2 = 112 & 112 removed 1= 12**As set of letters:**

```
ELEVEN + TWO = ELEVENTWO
& ELEVENTWO - ONE = LEVETW = TWELVE.
```

So, is there any other expression like this?
