Casio FX 83 ES Calculator

Product Information

Sexagesimal Calculations • Performing the following types of sexagesimal calculations produces a sexagesimal result. - Addition or subtraction of two sexagesimal values - Multiplication or division of a sexagesimal value and a decimal value Appendix <#012> 2°20´30˝ + 39´30˝ = 3°00´00˝ Converting Values between Sexagesimal and Decimal Pressing e while a calculation result is displayed toggles the value between sexagesimal and decimal. Appendix <#013> Convert 2.255 to its sexagesimal equivalent. Inputting Expressions and Values k Inputting a Calculation Expression Using Standard Format Your calculator lets you input calculation expressions just as they are written. Then simply press the = key to execute it. The calculator automatically judges the calculation priority sequence for addition, subtraction, multiplication, and division, functions, and parentheses.

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. Basic Calculations (COMP) This section explains how to perform arithmetic, fraction, percent, and sexagesimal calculations. All calculations in this section are performed in the COMP Mode (N1). k Arithmetic Calculations Use the +, -, *, and / keys to perform arithmetic calculations. Example: 7 × 8 – 4 × 5 = 36 LINE 7*8-4*5= • The calculator automatically judges the calculation priority sequence. For more information, see “Calculation Priority Sequence”. With its compact and lightweight design, the FX-83ES is highly portable, making it ideal for students and professionals on the go. It comes with a protective hard case, ensuring that it remains safe and secure during transportation. My Albert 3 looks different to that one. I think mine is newer. The layout is completely different. 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.

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.

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. Independent Memory Overview • The following is a summary of the different operations you can perform using independent memory. So does anyone know of a handheld calculator which allows you to have commas after every third number? Manuals look like jargon to me, is it possible to add a comma? Or does your calculator have to come like that?

About this Manual • The MATH mark indicates an example that uses Math format, while the LINE mark indicates Linear format. For details about input/output formats, see “Specifying the Input/Output Format”. • Keycap markings indicate what a key inputs or what function it performs. Example: 1, 2, +, -, !, A, etc. • Pressing the 1 or S key followed by a second key performs the alternate function of the second key. The alternate function is indicated by the text printed above the key.

The A-level models have additional functions such as solving quadratics and simultaneous equations which can be useful at GCSE too, as well as Statistics functions that you don’t need until A-level. So if there’s any chance of you continuing with Maths beyond GCSE then it’s a worthwhile investment. (You’ll probably need it if you do Core Maths too, though it does depend on which board and which modules you study. It – or an equivalent – is certainly required for the Statistical Techniques option on the AQA spec.) For GCSE Maths, you will need a scientific calculator, but just about any model will do; see AQA’s guidance below for a list of the functions you need.

It’s also worth considering an A-level model, especially if you’re doing the Higher Tier and there’s a possibility that you might continue to study Maths in some form beyond GCSE.
