• Touch PROGRAM, type IIEQUATION MATH, and ACCPT
• Type IICP TABLE D for the title of your custom program
• Touch the STOP key when the program is finished.
RUN the custom program:

Sub-totals
To obtain sub-totals in a statistical document, you write another equation. Sub-totaling can be thought of as "adding non-consecutive columns down." In the example below, sub-totals
Now you'll type an equation document to sub-total and total. Since the first sub-total is for rows 1 through 3, the first equation will be Rl : R3. The second equation you write is to Sum Column 1 and put the answer in Row 4 Column 1. The next equation is R5 : R7. Then you write the equation to Sum Column 1 and put the answer in Row 8 Column 1.
The equation to total the number of students in the county is written as follows:

Output Options
When the custom program puts the answers in your statistical table, it uses the standard output options. Standard options means:
• No commas
• No decimal points
• No plus or minus signs
• No parentheses for negative numbers
To tell the 860 you want to change the output options, you put an OPT equation at the beginning of your equation document. The OPT is preceded by a CODE + 3 and followed by a return. When you run the IIEQUATION MATH program, it will ask you which output options you want. The output options you select will remain in effect unless you enter another OPT equation and change the options.
In this exercise, you'll recall TABLE E and change the number of students in each school.
