### 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!
