| * |
: |
multiplication |
| % |
: |
calculate percentage (e.g. 50 * 20% = 10) |
| / |
: |
division |
| 1/x |
: |
divides 1 by the given number |
| x^2 |
: |
square: multiplies a given number with itself |
| = |
: |
get result |
Shortcuts and hints:
- x^n : for exponentiation, keep hitting '*', e.g., to calculate 5^4 key in : 5****
- To add the same number, keep hitting '+' : 3+2++++... = 2+3+3+3+3+3...
- To multiply with the same number, keep hitting '*' : 3*2****... = 2*3*3*3*3
(Note that is the FIRST number which is repeated!)
Limitations:
- avoid number overflow!
- only two decimal places available!
- there is no rounding in the multiplication result
To my knowledge this is the first Zillions game that handles very large numbers. This has been achieved by using positions-flags as temporary storage for the information (one position per digit). Feel free to copy this technique.
