Calculations can be input in the same form as they are written. When you press the priority sequence of the input calculation will be evaluated automatically and the result will appear on the display. Technical amendments and errors excepted. The sizes in figures do not correspond to the original sizes. Example: To determine the number of permutations and combinations possible when selecting four people from a group of 10. When Linear Display is selected, pressing will cause the cursor to jump to the beginning of the calculation, while will jump to the end. You can use the following procedure in the EQN Mode to solve simultaneous linear equations with two or three unknowns, quadratic equations, and cubic equations.

To solve 2 x 2 + x - 3 = 0, for example, press in step 2, and then input the following for the coefficients (a = 2, b = 1, c = -3): 2 1 3 . You can input up to 99 bytes for a calculation. Each numeral, symbol, or function normally uses one byte. Some functions require three to 13 bytes. Before starting a calculation, you must first enter the correct mode as indicated in the table below. The calculation result for r and θ and for x and y are each assigned respectively to variables X and Y. Press (EQN) and then select an equation type from the menu that appears. Changing the equation type causes the values of all Coefficient Editor coefficients to change to zero.Non-programmable scientific calculators fx-85ES PLUS 2nd edition Redesigned ES PLUS series calculators Even if Natural Display is selected, the solutions of simultaneous linear equations are not displayed using any form that includes √ . Pol converts rectangular coordinates to polar coordinates, while Rec converts polar coordinates to rectangular coordinates. The following operations are not supported by the Coefficient Editor: , (M-), (STO). Pol, Rec, and multi-statements also

The materials used in ES PLUS series calculators comply with European RoHS environmental regulations, an international standard. The keys have been made rectangular, making them easier to press. They are also easier to read because of larger text. Input of the closing parenthesis is required for sin, sinh, and other functions that include parentheses. This will display a solution. Each press of will display another solution. Pressing while the final solution is displayed will return to the Coefficient Editor.FX-82ES Plus, FX-85ES Plus, FX-350ES Plus, FX-570ES Plus and FX-991ES Plus emulation software for school calculators Since ES PLUS calculators are products used for many years as learning tools, the keys are made of a material that offers high durability and resistance to print peeling. To change a coefficient value you already have input, move the cursor to the appropriate cell, input the new value, and then press . Note: This differs from the actual colors because color shades vary depending on the direction of the light. thereshoulfbeabuttononyourcalculatorwhichlookssomethinglikeS<->D.sowhenyougetanansweranditsinfractionspressthatbuttonanditconvertsittodecimalsandnormalnumbers.Hopethathelps

The Natural Display (Natural-V.P.A.M.) shows mathematical expressions like roots and fractions as they appear in your textbook, and this increases comprehension because results are easier to understand.

When Natural Display is selected, pressing while the cursor is at the end of the input calculation will cause it to jump to the beginning, while pressing while the cursor is at the beginning will cause it to jump to the end. The outstanding FX-ES emulator features the same basic functionality as theFX-82ES Plus, FX-85ES Plus, FX-350ES Plus, FX-570ES Plus and FX-991ES Plus school calculators.

These multiplication symbols (×) can be omitted. A multiplication symbol can be omitted when it occurs immediately before an opening parenthesis, immediately before sin or other function that includes parentheses, immediately before the Ran# (random number) function, or immediately before a variable (A, B, C, D, E, F, M, X, Y), scientific constants, π or e.
