【實用解謎app】Sum It All Up|最夯免費app-綠色工廠好玩App

Sum It All Up for Android devices is a simple, addictive and educational game which gives you the answer to a mathematical problem and your task is to find the calculation that gives that result. Using all of the given numbers and any combination of addition, subtraction, multiplication and division, arrange them to get the correct answer.

There are 4 levels of difficulty each containing 4 stages. Each stage contains 50 unique math problems which should be plenty to be getting on with. Hints are available to help you get along but remember, you are up against the clock. Gold, silver or bronze stars are awarded if you complete the level on your 1st, 2nd or 3rd attempt at a problem.

Additionally, two 'Show Working' modes are available, doubling the total number of problems to solve. With 'Show Workings' switched 'ON', the answer to your working calculations are shown as you go along, to give you an idea of the answer so far. With 'Show Workings' switched 'OFF', the answer is hidden until the end, so things are a little trickier.

So grab yourself a copy and see how many gold stars you can get. Have fun, enjoy and maybe even help you maths problem solving skills.
