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.

If you have a Casio fx-83ES that is no longer working, you can first try replacing the AAA battery. If that doesn't solve the problem, then you can consider replacing the calculator with a modern equivalent.

I think mine is newer. The layout is completely different.

All of the models mentioned above are allowed in any exam where calculators are permitted *; there is no distinction between a calculator for GCSE and one for A-level as far as JCQ (who make the exam regulations) are concerned. You can find the JCQ regulations in section 10 of this document.

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”.

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.

Can anyone recommend a decent scientific calculator, with the ability to add commas after each third number?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. The standard GCSE model in the UK for the past seven or eight years has been the Casio Classwiz fx-83/85GT X (centre in the image), though in early 2023 Casio brought out the fx-83/85GT CW, which is very different and which has replaced the GT X (despite a poor reception from UK Maths teachers). More on that in this blog post. 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”.
