Mathpuzzler
Mathpuzzler is an Android mental arithmetic app that produces fresh maths puzzles using the four basic operations: +, −, × and ÷. Each puzzle is randomly generated, giving students and adults unlimited practice in mental maths, number skills and everyday arithmetic.
First Steps
We believe that the first step forward is recognising that poor numeracy can have an adverse effect on a person’s self-esteem and confidence when performing calculations in their head.
Improving mental calculation skills can have a positive impact on both learning and applying mathematics in everyday situations.
Our aim is to help young people and adults develop and strengthen their numeracy and mental arithmetic skills in a way that is engaging and enjoyable.
Magic Squares
Magic Squares have the unique property that the numbers in each row, column and diagonal always add up to the same value, known as the magic number. In this example, the magic number is 15.
