Note:
You will need to record your work and post it on the designated platform.

Instructions (II):

1. Add up the last 5 digits of your NRIC number. This 2 digit number “XX” is what you will convert from a decimal system to a binary system.
2. DO NOT RECITE OUT YOUR ENTIRE NRIC NUMBER ON THE VIDEO FOR SECURITY REASONS. You only need to state the last 5 digits on video.

• Research on how to count in binary system using the digits “0” and “1”.

• 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.

• how you identify the key information
• why you choose a particular method to solve the problem
• explain how the method works
