Chapter 3: Basic Calculations - Basic Keyboard CONCEPT PROCEDURE 1. Enter a math expression, then perform the calculation. 2. Save a number into a variable, then recall the value later. 1. First, press #, then C to clear any screen entries. 2. Type 186282 = 7.5, then press E. The circumference of the earth is thus obtained. Note: 3. Store the answer in a variable. A variable is a symbol under which you can store a numerical value. We will use variable A to store the circumference of the earth. Press R to set the "store" mode. Press A A, then E to store the answer. To call up the stored answer, press A A E again. While checking the stored values, you may see "0"; this means that no value is stored in the variable. 4. Now, since the value you have stored under "A" is the distance you will be travelling in 24 hours, divide the number by 24. Press A A = 24, then E. So, you are travelling at 1034.9 miles/hour. That is fast! 32
