The 82MS scientific computing tablet is an innovative intelligent device integrating professional scientific computing and digital handwriting recording. It adopts a folding and portable design, integrates dual-power power supply technology and high-precision induction technology, adapts to the learning and work needs of students, researchers, engineers and other groups, and realizes an integrated solution of "calculation-recording-creation".

First, the core scientific computing function
The equipment has built-in full-function scientific calculation module, equipped with 240 kinds of operation functions, covering the whole scene requirements from basic arithmetic to high-order scientific calculation, and the operation response speed reaches millisecond level ("82ms" is named after its efficient operation response characteristics), with both accuracy and stability.

Multi-mode operation support: It includes three core modes: basic arithmetic, scientific calculation and statistical regression. It can realize functions such as trigonometric function, hyperbolic function, exponential logarithm, permutation and combination, factorial, random number, negative number calculation, percentage operation, etc. At the same time, it supports the rapid call of common constants such as pi and natural constant e, which meets the complex calculation needs of middle schools, universities and scientific research scenes.

High-precision display and operation: equipped with 12-bit double-line LCD high-definition display screen, which can display calculation formulas and results synchronously to avoid omission in the operation process; The key is made of high-sensitivity plastic material, which is more accurate in touch and faster in response than the silicone key. With the logical key layout, the common functions can be directly reached by one key, which lowers the operating threshold.

Advanced computing power: Support logarithm exchange operation, equation solving, definite integral/indefinite integral calculation, limit and derivative operation, matrix operation and statistical analysis (average, median, standard deviation, etc.), and can generate data charts to assist intuitive understanding, which is suitable for deep application in mathematics, physics, engineering and other disciplines.

Storage and backtracking function: Built-in memory storage unit can save intermediate calculation results, support multi-step backtracking review, facilitate modification and reuse of complex operation processes, and improve calculation efficiency and accuracy.

Second, the digital handwriting creation function
Integrated 6.5-inch LCD handwriting board, using pressure sensing technology, giving consideration to writing fluency and erasing convenience, realizing paperless recording and creative expression, and seamlessly connecting with computing functions.

Accurate handwriting sensing: it supports special electronic pen writing and has pressure sensing function, which can adjust the line thickness according to the writing strength and restore the writing texture of paper and pen; The writing life can reach 100,000 times, which is wear-resistant and durable. It is matched with 5 spare pen heads to meet the long-term use requirements.

Convenient editing operation: equipped with a one-button erase button, it can quickly erase handwritten content, and support switching between partial erasure and full page erasure; Add the lock button to prevent the important notes from being erased by mistake, and ensure the recording safety.

Multi-scene creation adaptation: it can be used for scenarios such as calculation process deduction, formula draft drawing, mind map sorting, graphic annotation, list recording, etc. Handwritten content can be compared with calculation results to help logic sorting and thinking presentation.

Third, the hardware design and adaptation function
With portability and stability as the core, durable materials and flexible adaptation design are adopted to meet the needs of multi-scene use, taking into account endurance and compatibility.

Folding portable design: the overall size is 162*85*17.5mm, and the weight is only 135g g. The folding structure can effectively protect the screen and buttons, which is convenient to carry in schoolbags and pockets, and is suitable for classroom, laboratory, office, outdoor and other scenes.

Durable materials and technology: high-strength durable plastic shell, treated by ultrasonic technology, anti-fall and scratch; The board is covered with a matte brightness enhancement projection film, which is non-reflective and anti-glare, and can be used in conjunction with projection to adapt to teaching demonstration scenes.

Fourth, additional value-added functions
Personalized customization: supports logo customization and packaging customization, which can meet the needs of enterprise procurement and gift customization, and adapt to batch procurement scenarios.

Low power consumption and environmental protection: LCD handwriting screen has no backlight design, only consumes a small amount of electricity when erasing and writing, and cooperates with dual power supply to further reduce energy consumption and practice the concept of paperless environmental protection.

V. Summary of applicable scenarios
With the dual core advantages of "calculation+handwriting", the equipment is widely suitable for many kinds of scenes: students can be used for classroom study, homework calculation and pre-test review; Scientific research and engineering technicians can be used for data calculation, experimental records and scheme deduction; Teachers can be used for classroom teaching demonstration and formula derivation; At the same time, it can also be used as an efficient recording tool and gift selection in daily office, giving consideration to practicality and innovation.
