The EL-510RNB performs over 160 advanced scientific functions and utilizes an extra-large 11-digit LCD numeric display. The unique playback feature makes scientific equations easier for students to edit and run multiple simulations. It is ideal for students studying general math, algebra, geometry, and trigonometry. In addition, Direct Algebraic Logic (D.A.L.) makes entering an equation as simple as typing it in exactly as you would write it.
