Scientific calculator with equation recall combines statistics and advanced scientific functions. Two-line display shows entries on the top line and results on the bottom line. Entry line on the top of the display shows up to 11 characters and can scroll left and right up to 88. Result line on the bottom shows up to a 10-digit answer and 2-digit exponent. Functions include common/natural logarithms, fractions, fraction/decimal conversions, degrees to decimal conversion, reciprocals, factorials, grads, hyperbolics, polar/rectangular conversions. Fraction feature allows operations with fractions and mixed numbers. Two-variable statistics allow you to enter, delete, insert, and edit individual statistical data elements. Calculator runs on solar and battery power.

    I bought this to replace an old sharp scientific calculator that died after 20 years. This is a scientific calculator that has a two line display for inputing larger equations. However, equations are often removed when you enter equal, leaving ANS. in the display followed by your next inputs. It would be better to leave the previous equation as long as there is space on the display. It will perform all necessary Trig. and algebraic functions. It does lack certain conversion functions such as temperature and metric conversions. The model cannot have everything, but for a scientific calculator, it would be nice to not have to do manual metric conversions. All in all, it is a sufficient calculator for basic math, but there are better calculators with more functions for heavy scientific use.
