Formula memory
Frequently used formulas or complex equations can be stored as functions in Formula Memory. By recalling the formula, you can substitute new variables into the equation and recalculate it without having to enter the entire sequence again. Since you can do repeat equations, it's also convenient for simulations.
• How to Use It
Store the equation into the calculator.
You can put four equations into formula memory with the F1-F4 keys.

Direct Algebraic Logic (D.A.L.)
Until the introduction of SHARP's D.A.L., keying in equations had been a complicated process making scientific calculators difficult to use. Introduced in 1992 and an industry-first, SHARP's D.A.L. allows symbols and numbers of an equation to be entered as they are written. Instead of wasting energy on difficult calculator operations, users are free to concentrate on mathematical concepts.

Multi-Line Playback
SHARP's Multi-Line Playback function lets you recall the steps you have made (up to capacity of memory). This feature is very useful for comparing formulas and recalculating equations.

Constant/Chain Calculations
Constant and Chain Calculation functions are popular in general electronic calculators as they allow equations to be entered without having to key repeatedly. Confusion may arise however, as not all scientific calculators show the equation being equal to the answer in the formula display. With SHARP's scientific calculators, the figures you omit are automatically shown as K (constant) or ANS (answer). Contradictions between equations and answers are eliminated and calculations are easier and more logical to enter.

Numerical Derivative/Integral
Simply enter numerical values following the interactive on-screen instructions, and you can find the answer easily of derivative and integral calculations. You don't have to re-enter the formula, and the calculation can be repeated as many times as needed.

2-Key Roll-Over
Enables quick input of a keystroke, even if you still have a finger on the previous key.

Solver Function
This function enables calculation of a variable X in a given equation. Other variables (a, b, c, etc.) must already be defined in order to calculate X.
