, DSC1630/SOL02
Dear student
The solutions to the questions of the compulsory Assignment 02 are included in this document. Study
them when you prepare for the examination. We have added comments on how to approach each
problem.
You will also find the key operations for the SHARP and the HP calculators, as well as newer versions,
at the end of each answer. I hope it will help you to understand the workings of your calculator. Just
remember that these key operations are not the only method, these are just examples.
You can use any method as long as you get the same answer. Please download the calculator
notes/booklet from myUnisa under Additional Resources.
REMEMBER TO CLEAR ALL DATA FROM THE MEMORY BEFORE YOU ATTEMPT ANY
CALCULATIONS.
• SHARP EL-738 and newer versions users: Press 2ndF M-CLR 0 0 if you wish to clear
all the memories and 2ndF CA if you want to clear only the financial keys.
• HP10BII and newer versions users: Press C ALL
Note: the final answer displayed on your
calculator depends on how many decimals your
calculator’s display is set to. Set it to 6 or more
decimals and only round off the final answer to
the required number of decimals as given in the
options of the answers.
