The level of this examination extends no further than relatively simple geometry. Most problems can be solved using only arithmetic. By reading this chapter carefully, following the sample problems, and then working on the practice problems in each section, you can review important concepts and vocabulary, as well as familiarize yourself with various types of questions. Since arithmetic is basic to any further work in mathematics, this chapter is extremely important and should not be treated lightly. By doing these problems carefully and reading the workedout solutions, you can build the confidence needed to do well. 1. ADDITION OF WHOLE NUMBERS
In the process of addition, the numbers to be added are called addends. The answer is called the sum. In writing an addition problem, put one number underneath the other, being careful to keep columns straight with the units’ digits one below the other. If you find a sum by adding from top to bottom, you can check it by adding from bottom to top. Example: Find the sum of 403, 37, 8314, and 5. Solution: 403 37 8314 + 5 8759 Exercise 1
