ReMaths

Repeat. Remember. Results!
Like any game, if you don't know the rules, you can't play the game. Maths is like playing a game. Know the rules, play the game.
ReMaths has been created using simplified depictions of key maths rules that have been tried and tested by many students in the past, with great results.
ReMaths is split up into four groups. Select the group that corresponds to your education level, and start swiping through the rules. You don't need to spend long on each rule, just long enough for the information to sink in, then move on to the next. The more you do this, the easier it'll become to remember them.
ReMaths will count the number of times you complete a group. See how many times you can cycle through every rule in a group. Each group has a contents page, in case you need to find a specific rule.
You may develop your own way to use the app to aid your maths learning and start seeing results, but like any skill, repetition is key.
