I have to admit that I'm rubbish when it comes to maths. I always have been. This meant that at school I became very close friends with my calculator and would carry it wherever I went.
These days I leave it at home, but there are still times when I wish I had my trusty companion with me.
Thanks to the magic of mobile phone technology it's now possible to have a powerful calculator in your pocket at all times.
Solution is one of a number of calculating apps available for cellphones, and proves to be one of the best.
The software is designed to compute any mathematical problems, from basic algebraic calculations to complex scientific processes.
Solution's programmable user interface is surprisingly easy to navigate thanks to large, clear icons that allow you to quickly select the type of calculation you wish to perform.
There are oodles of functions locked in there, including addition, subtraction, multiplication and division; trigonometry functions, bases, graphical analysis, exponential and logarithmic functions, and lots of other stuff I don't really understand.
On top of this it boasts a number of advanced features that allow you to solve matrices, limits, differential equations and define integrals.
Personally, I would have liked to see some kind of explanation of what all of this means in layman's terms, but I guess if you're the sort of person performing these type of equations you know what you're doing anyway.
