Your calculator is fine. It is an adding machine first, so it uses adding machine logic and you hit the star button to print the total on the tape. The equals sign is only used when multiplying and dividing.
Adding machine logic is as follows:
5+ total 5
3- total 2
7+ total 9
* print out total
While in the D position or PD position, N Count is OFF. In the N Count N position every Plus, Minus, Equals Plus, Equals Minus, Memory Plus or Memory Minus key depression is counted. The Accumulator and its N Count or the GT N Count can be printed by depression of the Subtotal or Total key. When either Memory Subtotal or Memory Total is depressed, Memory N Count will print. N Count is always printed in red, left justified. If the Equals key is depressed immediately after the Subtotal Total, Memory Subtotal, or Memory Total the average of the entries is printed. When the N Count prints on the 7150, an audit symbol will print to the left of the N Count. The audit NA will identify the Accumulator register N Count, NG will identify the GT register N Count and NM will identify the Memory N Count.
To calculate 7-2=5 (for example) on a business calculator: 7 + (all positive entries are followed by the + key) 2 - (all negative entries are followed by the - key) * (The Total key, marked with a star or a T finishes the calculation.)
It seems strange to people who use handheld calculators, but this is how adding machines have worked since the days of hand-cranked adding machines. The subtotal key (marked with S or a diamond) prints the running total without clearing it back to zero.
The grand totals are about the only thing that cannot be reset (they are called non resettable grand totals) so you can just turn them off. turn key to program 3 SUBTOTAL 0822 SUBTOTAL 2000 CASH SUBTOTAL Now turn the key to Z mode and press CASH. The machine will print a daily report. Now press CASH again and you should get a small clear report with nothing on it. now you are ready to go. turn key back to REG mode
Please try this:- go to PGM-3 select key features select function key- hit sub total see detail functioning of sub total. if you find any link delete it and hit esc.key till you reach in original mode .
Subtotal is only hit after all sales...Labor or merchandise have been entered, then you hit the tax button, subtotal and then enter the amopunt of money handed to you and the CA/ Amt Tendered button...all tax will be added and tell yo the change to give back!
This is a very handy process when you're totaling or subtotaling columns. On the cell that you want the 'total' in type '=sum(column letter row number),(column letter row number). The first 'column letter row number' is where you want the first cell to be started in the total factor and the second 'column letter row number) is the last cell you want added in the total factor. The help (?) section is good at explaining formulas. Hope this helps, keep this process handy if you use Excel much because it'll be helpfull each time you subtotal or total columns.

Use the function =sum() to add numbers. To sum, for example, all of column A, enter in the formula bar =sum($A:$A). You can use the subtotal function within the range you are adding and the answer will not count towards the final total.
