Chapter 3: Basic Calculations - Basic Keyboard b Enters a fraction, setting the preceding number as its numerator. ¬ ¬ * If the calculator is set to one-line mode, then " " will be entered instead. For example, "2 5" indicates " 2 5 ". Example • Calculate 2 5 + 3 4 . 2 b 5 ' + b 3 ' 4 ' E a Note: Enters an exponent, setting the preceding number as its base. Example • Raise 4 to the 5th power. (= 1024) 4 a 5 E When no base value is entered, "ab" will be entered with both number areas left blank. C a ; 4 ' 5 E When calculating x to the power of m-th power of n, enter as follows; • Calculate 232 (= 512) 2 a 3 a 2 E The above calculation is interpreted as 232 = 29. If you wish to calculate (23)2 = 82, press ( 2 a 3 ' ) a 2 E. , Enters a comma " , " at the cursor. A comma is required in some of the MATH functions. For more information, refer to the next section "Calculations Using MATH Menu Items" in this chapter. R Stores a number in a variable. Example • Let A = 4, and B = 6. Calculate A + B. 4 R A A E 6 R A B E A A + A B E 38
