Adding Machine Instructions

1. Add and subtract on the adding machine by pressing each number followed by its mathematical sign. For example, press the '6,' '+,' '7,' '+,' '-4' and '=' buttons for the equation '6 + 7 + (-4) = 9.'
2. Multiply and divide by pressing a number followed by the sign and then the next number. For example, press '6,' 'x,' '6' and '=' for the mathematical equation '6 x 6 = 36.'
3. Press the 'Up' arrow on the adding machine to advance the paper up without printing. The arrow pointing to the right removes the last digit entered.
4. Choose the 'M+' button to save the currently displayed value into the adding machine memory. An 'M' will display on the screen. If you press it again, it will add the new amount to the existing memory. If you want to subtract the currently displayed value from the memory, press the 'M-.'
5. Press the 'M' with a diamond shape next to it to print the value stored in the memory without erasing it. The 'M*' button will print the stored memory and clear it.
6. Clear every operation in progress by pressing the 'C' key. This will not erase any stored memory. The 'CE' key will clear the screen, but will not clear any operations in progress.
7. Display and print the subtotal by pressing the diamond key. The adding machine will remember the total for the following entry. Press the '*' key to print the current total and set the machine back to zero.
