Here is what you have to do:

- Generate questions at random by clicking
**Get Questions**button. - Enter your answer in the text box.
- Check the answer by clicking
**Check Answer**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!
