About this product
Product Information
Get ready to solve difficult math equations, including algebraic equations, quickly and easily. The HP-20S programmable scientific calculator is a wonderful accessory for students. The 20S will take them from middle school pre-algebra through college calculus and more advanced science and mathematics courses. Young mathematicians will progress rapidly through algebra with the 20S thanks to its intuitive algebraic entry system. This allows students to enter data into the calculator algebraic notation, just as it appears in test or homework questions. This feature is especially useful when doing complex mathematical operations of solving equations that require many steps. After writing their work out on paper as required, students can check their work with the 20S. If the student has the wrong answer, they can input each step into the calculator to find the error.The HP-20S scientific calculator will continue to serve students well as they progress to higher mathematics courses. It will display up to 12 digits at a time. Advanced calculus students can take advantage of the formula button for Simpson's Rule of Integration. Data science students will save time with the 20S when they use the built-in curve fitting programs. The standard programs in memory also include quadratic formulas, 3x3 matrix operations, and complex mathematical operations. To access the program library in memory, press left shift key, delete key, load key. You can then use the letters A-F to access program groups. A calls the root finder. B is for numeric integral programs. Choose C for complex number arithmetic. D accesses matrices, and E is the quadratic equation solver. F is for exponential, logarithmic, and power regression functions.Business professionals can also find plenty of use for this scientific calculator, which comes with over 150 essential functions. Some the standard conversion features on the 20S include distance in centimeters to inches and mass in pounds to kilograms. Baking Continental recipes become a breeze with the built-in volume conversions like milliliters to teaspoons, tablespoons, or fluid ounces. Distance conversions while traveling is a snap, with the pre-programmed mile to kilometer conversion function. Fashionistas will find the pre-programmed size conversion feature, including centimeters to inches, which is handy when purchasing clothing in European sizes.Students will enjoy the ease of the root-finding feature and the quadratic formula shortcut. Trigonometric functions available at the touch of a key include sine, cosine, and tangent. Other essential math shortcuts already programmed in include exponential, log, and antilog keys. Students can also input their own equations and programs to this Hewlett Packard calculator with the programmable keystroke feature. This lets the student automate specific routine equations or programs for certain classes and topics. Many teachers allow students to store specific equations in their calculator's memory for use during tests. The HP-20S fits in a laptop case, briefcase, or purse, so it's always at hand when you need it. Even though the calculator has a compact size, the keys are not, making them easy to see and use. This calculator comes with a vinyl Hewlett Packard slipcase to protect it through the years and requires three LR44 batteries.

Item was exactly as the seller described. It was packed well, but didn't arrive on time. The package was delayed due to no fault of the seller. Usps said there was a delay due to weather issue. The seller assured me and did her best to communicate and update tracking. She was kind and helpful in everything. I am very happy with my purchase and wish the seller the best and would definitely buy from her again.
