Scientific calculator is a type of electronic calculator. It can be performed by multiplication, opening, index, pairing, triangular functions, statistics and other aspects, also known as function calculators.Scientific types have all ordinary functions, and all functions are distributed on the keyboard so that they can be used without the menu list.
Scientific calculator case function description
There is a memory in the calculator, which is empty (that is, 0) in the default state.It can save any value and can only save one value.You can treat it as a box that can only save one thing.
MS: Save the currently displayed value
Mr: Read the value in the memory and display it
MC: Clear the existing data
M-: After minus the currently displayed value with the existing value, then save the result
M+: After using the existing value plus the currently displayed value, then save the result
RCL: View variables
Computers have four states: NORM, FIX, ENG, SCI, the functions are: specify the index mark range, decimal point setting, engineering computing, effective digital settings.If the calculator is in the other three states, operational errors may occur.
DEG is the state of setting the angle of the calculator. There are six types:
DEG -specification is used as a default unit.
RAD -specify the arc as the preset unit.
GRA -specified gradient as the preset unit.Also known as "percentage" and "new degrees".
° -Specify a unit for a certain input value.
R — Specify a unit of an input value.
G — Specify a unit for a gradient as an input value.
Sometimes if the angle (DEG) is mistakenly set to the arc (RAD) or gradient (GRA) state, the calculation result error °, R, and G are used to identify an angle unit.
So to eliminate GRA, you can find the calculation mode switch.

Method III. Call this machine program through the webpage to achieve all the functions of the online calculator.
After opening the program, you can click "View" to switch between standard, scientific, programmer and statistical information.
Precautions for the use of scientific calculators
1. When using the calculator for the first time, please press the ON key.
2. Even if the operation of the calculator is normal, it still needs to be replaced at least every three years.Expired batteries may leak, causing damage or abnormal function of calculators.Do not put the expired battery in the calculator.
3. With the battery attached to the calculator, mild power may be lost during the storage and transportation process.It may need to have less life span than normal battery, and change it earlier.
4. Insufficient electricity may damage the content of the memory device or disappear forever.For important data, there should always be a record of the picture.
5. Avoid storing or using calculators in areas exceeding the temperature limit.Using at a very low temperature may cause the display delay, or the display screen is completely damaged, and shorten the battery life.In addition, the calculator should be avoided by direct sunlight, near the window, near the electric heating device or any place exposed to high temperature.High temperature may cause the computor case to fade or deform and cause damage to internal circuits.
6. Avoid storage or calculators in areas with high humidity and high dust.Be careful not to let the calculator be poured into the water, or the environment exposed to high humidity and high dust.This situation will damage the internal circuit.
7. Dont fall the calculator or let it be strongly hit.
8. Do not twist or bend the calculator.Please do not place the calculator in the pants pocket, or other tight clothes, because this may be twisted or curved by the calculator.
9. Do not disassemble the calculator.
10. Do not use atomic pens or other sharp items to press the button of the calculator.
11. Use the dry cloth cleaning calculator of a soft and cleaned oscilloscope.If the calculator is stubborn, wipe the soft cloth diluted with the use of household cleaners and water diluted solutions.Squeeze too much water before wiping the calculator.Do not use diluents, benzene or other volatile solvents to clean the calculator.This will wipe off the printing pattern and damage the calculator shell.
