Adding machines are similar to calculators in use. However, adding machines provide more functions when calculating numbers. Adding machines are used by many individuals and businesses; the financial industry is a particularly heavy user of them. Most of these machines include printing tape to record all the numbers calculated. This provides a paper record for double-checking work. Adding machines also have special memory capabilities, so users do not always need to press the function keys when calculating numbers.
Step 1
Load printing tape into the adding machine. Most machines let the user decide whether to use the tape.
Step 2
Enter numbers into the machine.
Step 3
Press the "+" key to add more numbers to the original figure.
Step 4
Press the "Total" or "*" to compute the final figure.
Step 5
Review the tape to look for any errors in the final total.
Step 6
Press the "Clear" key to erase the figure and add a different set of numbers.
