Product Information

Trust Texas Instruments to provide an efficient solution to challenging math-based problems. Anyone can quickly compute the correct answer to complex scientific and statistical equations using the Texas Instruments TI-55. Designed with a sharp LED display, this calculator provides high-quality performance. Users can program the TI-55 with up to 10 memory registers to store frequently used calculations, algorithms, and trigonometry. The built-in factorial function makes even complex factorial equations no match for this calculator's proven technology. Weighing only 6.4 ounces, the portable TI-55 calculator is lightweight enough to carry back and forth to school, home, or the office.The TI-55 is a programmable calculator developed by Texas Instruments in the USA. Some of the top features included with this modern device are an LED display and the ability to be programmable to hold up to 32 key codes, which allows the user to repeat primary calculations with assorted values by programming the keys differently. Texas Instruments developed these dependable calculators for engineers, but anyone can appreciate the extra key codes that lend for programming specific formulas. This TI calculating unit is one of the early LED programmable calculator products from Texas Instruments. This scientific calculator performs a basic set of scientific and statistical functions, and the ability to program more functions makes it a versatile piece of equipment for any working professional or student. Texas Instrument's model 55 scientific calculator has a memory capacity of 10, a red display of 12 LEDs, and a 40-key display. It uses two nickel-cadmium AA size batteries to operate. You can use one of these calculators as a basic statistical tool or take advantage of this scientific calculator to figure algorithms, algebraic sums, and trigonometry. Program dozens of formulas right into the calculator to suit your needs.The red display made of LEDs gives a visual impact, and clarity for the user, which is much easier to see than the LCD screens. The keys are manually pre-programmed for sine, cosine, logarithm, tangent, inverses calculated in degrees, and grades. Texas Instruments calculators perform natural base E logarithms in addition to common base 10 logs, sigma, and hyperbolic calculations with very intuitive statistical capabilities; you can utilize the functions of mean, variance, standard deviation, linear regression, and line trend analysis. Some of the other pre-programmed keys are stored data, recall data from M, and exchange the contents of the memory with a display value. It performs factoring, square roots, and squared functions, and this unit has the universal power key to the second or third power, not on or off. It can configure products and sums, and it calculates the best fit in linear regression for the least squares line in statistics. This Texas Instrument calculator also performs universal squares and square roots. It has a permanent storage for the last calculation so that when you turn off the device, the formula remains. This functionality has many practical applications in the workplace and school settings.
