# Scientific Calculator

**Scientific calculator introduction**

Scientific calculator is widely used in school works and statistic calculation. It has a flat shape , smooth touched keyboard with contrasting colors of keys for users’ convenient operation and checking numbers, its dual-powered design is solar-powered and battery inside for extended use. In addition to the basic functions, there are much more functions for mathematical formula operation and statistic calculation.

**FEATURES AND ADVANTAGES****:**

- Large LCD displaywith good quality, one line or two lines display can be made.

- Multifunctional calculations, normally in 56/240 functions， other functions can be discussed and developed.
- Ideal for mathematics calculation, trigonometric statistic, algebraic functions.

**FUNCTIONS:**

- Basicpurpose functions for simple calculation .
- Automatic priority of calculations, logic of calculations may be performed as expressed in the equation: 1)function calculations, 2) calculation in(), 3)power and root calculation, 4) multiplication and division, 5)addition and subtraction.
- Memoryfunction.
- Can be made the change sign (+/-) key which simplifies entry of negative numbers.
- Can be made the backspace key (→) which will correct the wrong numbers entered
- Automatic power-off functionis to conserve battery long lift time. Automatic power-off function that activates after approximately 7 minutes to save power.
- Fractions and decimal calculating.
- Open and close brackets make the calculation you need in priority.
- Can be made dual power drive supply, solar powered and battery backup are with long-lasting battery life and longer working time.
