When you're recording, it's important to get the sounds right. Ten key tape is a recording format that involves 10-inches of magnetic tape, also known as a reel, winding a total of 100 feet.

Judy's TenKey can process numbers like a scientific calculator (RPN), an adding machine, or a normal calculator. Unlike other calculators that make you pick a syntax and stick with it, Judy's TenKey lets you use any feature with any syntax. How many scientific calculators have you seen with a tape? Or adding machines that could calculate your mortgage? Judy's TenKey provides the ultimate in refined flexibility. If you are familiar with one and not another, you know how difficult and frustrating it can be to try to switch. Perfect for accountants, engineers, and everyone else!

Since its introduction in 1888, when it was patented by Williams Burroughs, the adding machine with tape has been a staple in office environments. However, they have become a dinosaur in the modern office, since hand-held tiny calculators can be found at every turn. Using an adding machine with tape provides advantages that you can't get from a hand-held machine, though. First, it lets you check your work immediately. Second, you have a permanent dated record of your work. Third, if working with long rows of numbers, you can do a side-by-side comparison. (Source: bizfluent.com)

Look for the additional keys on the machine. The key with the arrow pointed up is the paper advance key, which will allow you to add paper to your column of numbers without having anything printed on it. The key with the arrow pointed to the right will erase the last digit you've put into the machine. The "#" key will print a number on top of the tape without including it into the total. This is a useful key if you want to show a date on the tape. A key that reads "+0234F" is the decimal point selector key, which automatically defaults to two digits but can be adjusted to an infinite number. The key that has up and down arrows along with a fraction is how you select if you want figures rounded up or down when performing multiplication and division calculations. The other keys function in the same manner as a regular calculat.

Suppose you sold three items priced at 26.95, 14.75 and 9.99 and you must collect a sales tax of 6.25% along with the total purchase. Enter the following (+26.95 +14.75 +9.99 6.25% ). Your calculator tape will show the subtotal of 51.69, a 6.25% tax of 3.23 and a total of 54.92 as in the image below. (Source: www.calculatorsoup.com)
