Instructions (I):
 This is an individual task. Complete the viva voce task on your own.
 This is a reinforcement of similar questions based on the topic covered in class.
 It will also help you to seek and articulate your understanding of concepts as you attempt to explain
 your approach and solution to the problem.

Note:
You will need to record your work and submit via Google Classroom (Mathematics)
Remember to click "SUBMIT"/ "TURN IN" for the assignment to be turned in.
Otherwise it will be recorded as LATE.
Instructions (II):
1. Convert the last 5 digits of your handphone (use your home number if you do not have a handphone) "AAAAA” into a Babylonian number, using the Babylonian Number System.
DO NOT RECITE YOUR ENTIRE HANDPHONE NUMBER ON THE VIDEO FOR SECURITY REASONS. You only need to state the last 5 digits on video and explain the Mathematical process behind your conversion. 2. Using your birthdate "XX" as a 2 digit number and height “YYY” in centimetres as a 3 digit number, explain the simple arithmetic operation “XX + YYY” using Babylonian Number System.
 Research on the origin of Babylonian Number System.
 Explain briefly, in your own words, on how the counting method works.
 You may use any visualisation tools to help explain yourself.
 Work out and explain the solution clearly. You may choose to write it out,
 or use various software like Numbers to write your own script.
 Do not simply read out the lines of the working. Instead, inform the audience:
 how the conversion is done using Babylonian Number System
 how the addition is done using Babylonian Number System
3. Recording
 You may use QuickTime Player, PhotoBooth or any other suitable media to record your viva voce.
 Here are some ways that you can present your worked solution:
 You may sit in front of the computer and show the working (on papers) as you explain
 how you solve or problem using the "movie recording" feature in QuickTime Player;
 or simply "video recording" with PhotoBooth.
