ART. 25. WHEN it is required to find the difference between two numbers, the process is called Subtraction. The operation is the reverse of addition. Ex. 1. John has 7 oranges, and his sister but 4; how many more has John than his sister? ILLUSTRATION. To solve this question, we first inquire what number added to 4 will make 7. From addition we learn that 4 and 3 are 7; consequently, if 4 oranges be taken from 7 oranges, 3 will remain. Hence John has 3 oranges more than his sister. QUESTIONS. Art. 25.
