Writing Step 1: Below are the options that are to be used to randomly get your variable values for each
of the math statements, add, subtract, multiply and divide. Use the random pull for the various math
operations once only for the add, subtract, multiply, and divide Variables should be declared whole
numbers for add, subtract, and multiply, and declared as decimal numbers for divide and rounded to 4
decimals. Try it without rounding and see what happens!
Writing Step 2: Write the program using the random statement listed for the add, subtract, multiply,
and divide Testing items, T1, T2, T3, T4, testing each section as you first write it. If a change is needed,
fix it.
Note: that you can comment out sections of the program to only test one at a time by right
clicking the line of code and clicking Is Enabled and the check mark will be removed, and the
code will remain, but greyed out lines will appear and be ignored when you run the program. To
re-enable the code line, right click on the code line and click Is Enabled again and the greyed-out
lines will disappear as the code is now enabled to be used.
After coding all the parts in the program for the four math calculations, run your final test of all of them
at the same time.
Test Step 1: Run 1 will be the first complete run of your program with no code lines disabled. have the
addition statement in T1 Run 1, the subtraction statement in T2 Run 1, the multiplication statement in
T3 Run 1, and the division statement in T4 Run 1. Each of these math functions will be executed with
one run of the program and you will update the appropriate row with the values that were randomly
generated for this run and that row, following the addition example and using the appropriate math
symbol for the Test section.
Test Step 2: Without changing the program (unless there was an error to fix) you run the program again
for Run 2. Run 2 will be the second complete run of your program with no code lines disabled. have the
addition statement in T1 Run 2, the subtraction statement in T2 Run 2, the multiplication statement in
T3 Run 2, and the division statement in T4 Run 2. Each of these math functions will be executed with
one run of the program and you will update the appropriate row with the values that were randomly
generated for this run and that row, following the addition example, and using the appropriate math
symbol for the Test section.
Test Step 3: Without changing the program (unless there was an error to fix) you run the program again
for Run 3. Run 3 will be the third complete run of your program with no code lines disabled. have the
addition statement in T1 Run 3, the subtraction statement in T2 Run 3, the multiplication statement in
T3 Run 3, and the division statement in T4 Run 3. Each of these math functions will be executed with
one run of the program and you will update the appropriate row with the values that were randomly
generated for this run and that row, following the addition example, and using the appropriate math
symbol for the Test section.
Test Step 4: Without changing the program (unless there was an error to fix) you run the program again
for Run 4. Run 4 will be the fourth complete run of your program with no code lines disabled. have the
addition statement in T1 Run 4, the subtraction statement in T2 Run 4, the multiplication statement in
T3 Run 4, and the division statement in T4 Run 4. Each of these math functions will be executed with
one run of the program and you will update the appropriate row with the values that were randomly
generated for this run and that row, following the addition example, and using the appropriate math
symbol for the Test section.

multiplication.
T3 Random Statement.
Each run * statement
T3 Run 1
T3 Run 2
T3 Run 3
Q3 Run 4
nbr1 = 2 and nbr2 = 4
Example of run data for
division.
T4 Random Statement.
Each run / statement
T4 Run 1
T4 Run 2
T4 Run 3
Q4 Run 4
dec1 = 1.2081 and dec2 dec1 / dec2
Correct. Round to 4
= 3.7121
