Example: Input expression Calculation result { k Display Indicators Sample Display: This indicator: STAT Means this: S The keypad has been shifted by pressing the 1 key. The keypad will unshift and this indicator will disappear when you press a key. A The alpha input mode has been entered by pressing the S key. The alpha input mode will be exited and this indicator will disappear when you press a key. Equipped with a wide range of mathematical functions, the FX-83ES is capable of performing various calculations, including basic arithmetic operations, percentage calculations, and trigonometric functions. It also offers statistical calculations, allowing users to generate data plots and perform regression analyses. Displaying a Long Expression The display can show up to 14 characters at a time. Inputting the 15th character causes the expression to shift to the left. At this time, the ] indicator appears to the left of the expression, indicating that it runs off the left side of the screen. Input expression: 1111 + 2222 + 3333 + 444 Math Displayed portion: Cursor • When the ] indicator is displayed, you can scroll left and view the hidden part by pressing the d key. dddY s Overwrite Mode: c60) dddd s Inserting Input into a Calculation Always use the insert mode for this operation. Use d or e to move the cursor to the location where you want to insert new input, and then input what you want. k Displaying the Location of an Error If an error message (like “Math ERROR” or “Syntax ERROR”) appears when you press =, press d or e. This will display the part of the calculation where the error occurred, with the cursor positioned at the error location.

Calculation Examples Using Independent Memory • If the “M” indicator is on the display, perform the procedure under “Clearing Independent Memory” before performing this example. Example: 23 + 9 = 32 23+9m 53 – 6 = 47 53-6m –)45 × 2 = 90 45*21m(M–) 99 ÷ 3 = 33 99/3m (Total) 22 tm(M) Clearing Independent Memory Press01t(STO)m. This clears independent memory and causes the “M” indicator to disappear from the display. Inputting Answer Memory Contents into an Expression Example: To perform the calculations shown below: 123 + 456 = 579 789 – 579 = 210 LINE 123+456= 789-G= k Independent Memory (M) You can add calculation results to or subtract results from independent memory. The “M” appears on the display when independent memory contains a value.

Switching between Fraction and Decimal Format f • The format of the fraction depends on the currently selected fraction display format setting (improper fraction or mixed fraction). • You cannot switch from decimal format to mixed fraction format if the total number of digits used in the mixed fraction (including integer, numerator, denominator, and separator symbols) is greater than 10. • For details about the f key, see “Using S-D Transformation”. Important! • For a very complex calculation or some other type of calculation that takes a long time to execute, the display may show only the above indicators (without any value) while it performs the calculation internally.k Inputting with Math Format When inputting with Math format, you can input and display fractions and some functions using the same format as they appear in your textbook. Important! • Certain types of expressions can cause the height of a calculation formula to be greater than one display line. The maximum allowable height of a calculation formula is two display screens (31 dots × 2). Further input will become impossible if the height of the calculation you are inputting exceeds the allowable limit. The Casio fx-83ES is a scientific calculator with 10 digits precision and formula input logic. It has 249 functions, 50 keys, and an LCD (liquid crystal) display. The power source is AAA batteries. The calculator was manufactured in China. My Albert 3 looks different to that one. I think mine is newer. The layout is completely different. With Math format, you can only use the insert mode. Pressing 1Y(INS) when the Math format is selected does not switch to the overwrite mode. See “Incorporating a Value into a Function” for more information. • The calculator automatically changes to the insert mode whenever you change the input/output format from Linear to Math.
