### Practise Positive and Negative Number Addition & Subtraction

Here is what you have to do:

•     Generate questions at random by clicking Get Questions button.
•     Practise at least 50 questions; then, End the Session button will be activated.
•     Look at your score; it is automatically updated.
•     Reduce the time taken for each session as you make progress.

Initially, it may take a bit longer to do the fifty questions. As you practise more, it will be enjoyable and your efficiency will improve significantly.

Here are few tips:

8 + 6 + 3 = 17
8 + 7 - 2 = 13
12 - 5 + 7 = 14
9 - 5 -5 = -1
-7 + 8 -2 = -1
-8 - -5 + 4 = 1
6 - -7 + 2 = 15
12 - 4 - -3 = 11

If you want an excellent mathematical joke, please practise at least 50 questions. Have fun!

Await the Joke:

D Rayner has produced a wonderful collection of books in mathematics for GCSE or Junior/Senior High School students. These books contain a vast collection of questions, beautifully classified under every major topic, in order to provide the students the opportunity to practise and make remarkable progress.

### Resources at Fingertips

This is a vast collection of tutorials, covering the syllabuses of GCSE, iGCSE, A-level and even at undergraduate level. They are organized according to these specific levels.
The major categories are for core mathematics, statistics, mechanics and trigonometry. Under each category, the tutorials are grouped according to the academic level.
This is also an opportunity to pay tribute to the intellectual giants like Newton, Pythagoras and Leibniz, who came up with lots of concepts in maths that we take for granted today - by using them to serve mankind.
