SUBTRACTION LESSON 8 Subtraction is an operation by which the difference between two numbers is found. Only like numbers can be subtracted. Units must be taken from units, tens from tens, hundreds from hundreds, dollars from dollars, etc. The number from which another is taken is called the Minuend. The number taken from the minuend is called the Subtrahend. The number that is left after the subtrahend is taken from the minuend is called the Difference or Remainder. 1. John had 24 marbles and gave his brother 10. How many had he left? 2. A boy picked 84 quarts of berries and sold 34 quarts. How many quarts remained? 3.
