Android app practice exercises for Primary 6 (Sixth Grade) Maths Algebra.
You can practice with as many algebra problems as you wish: 5, 10, 50, 100, 200... there's no limit to the number of questions you can practice with!
The questions, numbers and answers are dynamically generated, so you don't have to worry about doing the exact same problem sum anytime soon.
After you have chosen your answer, the correct answer is highlighted in yellow.
The scores at the bottom of the screen shows the number of questions you answered correctly, those that you answered wrong, and those that you skipped, respectively. Try not to skip questions, and try to keep the score of the green tick higher than the other 2 numbers.
Practice makes perfect, and this is the perfect practice for you!
