Many challenges can be met when calculating. With the Dyscalculator, these challenges will become smaller and fewer.

The Dyscalculator is a regular calculator AND a helpful tool that:
helps you understand numbers.
helps you choose the arithmetic operation.

The more ways you experience a number, the better chance you have to understand it. In Dyscalculator numbers are presented in four different ways:
Number symbol (76)
Worded numbers (seventy-six)
Audio (numbers can be read out loud)
Graphical (numbers can be illustrated as bars)

A common mistake is to type in the digits of a number in the wrong order. With the Dyscalculator you can easily swap the digits around until you get the correct number.

Four new arithmetic operations will help you when you need to know how an arithmetical problem should be solved. The new arithmetic operations help you when e.g. the question could be: "What should I multiply with, when I have a recipe for 4 people, but I need it for 7?" Here you would type 4 x? 7 and get the result 1.75.

So helpful

Thank you, thank you, thank you. This app is so very helpful. I often mixup the order of numbers or become confused when I try to SAY the number that I know! Thank you so much, this is an invaluable tool.

You can only do one level of calculation on this calculator. What I mean is that for example, say that you are calculating hourly wage into yearly salary. Start with the hourly rate times forty then take that number and multiply it by twelve. But you can't! Don't take my word for it, try it and you'll see the flaw.
