 ## Calculator 
+A riddle is a math expression, e.g., `x * y =`.
+The values of the variables `x` and `y` are defined via text files, e.g., a line `x = 10` in text file assigns the value to `12` to the variable `x`.
 
-A riddle is a math expression, e.g., `x * y =` and the values of the variables `x` and `y` are defined via text files.
-For example a line `x = 12` in text file assigns the value to `12` to the variable `x`.
-
-For example, the result of a riddle `x * x =` would be `144` with the explanation `12 * 12 = 144`.
+For example, the result of a riddle `x * x =` would be `100` with the explanation `10 * 10 = 100`.
 
 ## Riddle Example
-In this example the values of the variables are [`x = 10`](./data/share/example/x.txt), [`y = 15`](./data/share/example/y.txt), [`z = 20`](./data/share/example/z.txt), see the files in [`./data/share/example/`](./data/share/example/).
