Subtracting involves finding the difference between two or more numbers. It is a method that can be used for a variety of applications, such as balancing a checkbook, planning a schedule, cooking, or travel. Suppose a government official is out of the U.S. on business for 142 days a year, including travel time. The number of days per year she is in the U.S. is the difference of 365 days and 142 days. Subtraction is one way of calculating the number of days she would be in the U.S. during the year.
When subtracting numbers, it is important to line up your numbers, just as with addition.
The minuend is the greater number from which the lesser number is subtracted. The subtrahend is the number that is subtracted from the minuend. A good way to keep minuend and subtrahend straight is that since subtrahend has “subtra” in its beginning, it goes next to the subtraction sign and is the number being subtracted. The difference is the quantity that results from subtracting the subtrahend from the minuend. In 86 – 52 = 34, 86 is the minuend, 52 is the subtrahend, and 34 is the difference.
Words associated with subtraction include minus, take away, remove and difference.
