Casio calculator power
1. For standard counting method, press Eng
extended data
1. There is a memory in Ms Mr MC M-M +
calculator, which is empty by default (i.e. 0). It can save any value, and only one value. You can think of it as a box that holds only one thing
(1) ms: save the value currently displayed
(2) MR: read the value in the memory and display it
(3) MC: clear the stored data
(4) m -: subtract the currently displayed value from the saved value, and then save the result
(5) m +: add the current displayed value to the saved value, and then save the result
RCL stoRCL is the viewing variable, sto is the assignment
3, DEG rad grad
(1) d (DEG) r (RAD) g (Grad) respectively represents the angle system, radian system and hundred degree system
(2) the computer has four states: norm, fix, Eng and SCI. The functions are: specifying index mark range, decimal point setting, engineering calculation and significant digit setting. If the calculator is in the other three states, calculation errors may occur
DEG is the state of setting the angle of the calculator to degree, there are six kinds:(1) DEG - specifies the degree as the preset unit
(2) rad - specifies radians as the default unit
(3) gra - specifies the gradient as the default unit. Also known as "Centennial" and "newness."
4 °— Specifies the degree as the unit of an input value
(5) r - the unit that specifies radian as an input value
(6) g-The unit that specifies the gradient as an input value
Hyp sin cos Tan ln log(1) sin cos Tan is trigonometric function, SIN-1 COS-1 tan-1 corresponds to anti trigonometric function, which is equivalent to arcsin, arccos, arctan
(2) Hyp is a hyperbolic function of sin, cos and tan (3) ln is the natural logarithm ln a = loge a (4) log logarithm function"press shift, 7, on at the same time" to enter the self check of 82, which is called self check for short
gy450x vere means that the main board of this calculator is gy450x, and the version number is e
sum 6379. OK means that the program code of this calculator is 6379, which is the same as expected and displays OK, The program code is different
PD - means that there is no P contact connected on the calculator motherboard. Connecting the P contact on the calculator motherboard will change p - into P1, P2, P3, one of them
and then press AC twice. 00 is to check whether the calculator key is normal
from shift, alpha, up, right, mode, ABS... Press down one by one (excluding on) until you press the = key. If the calculator key is normal, 00 will be added to 49 and test OK will appear.
declare again!! 82esplus no games!!!
off key (basically in the upper right corner of the computer)
if not, please try:
Shift + AC (shift key is the second function key. AC is basically near the +, - keys, and is basically red
if not, please search online or send the model< br />

you need to see if you need many functions in it.
991 es is the upgraded version of 991 MS, 991 -- es is the best of CASIO function calculation (excluding advanced function calculator). There are three kinds of special functions for finance and economics. In fact, it mainly depends on whether you need its functions
specifically, 82es supports natural display, that is, it can display the root number, the π And so on, just like in books, the design is for students
according to your situation, and Casio, 82ms has been eliminated, you can buy 82es, the price is about 50-70, pay attention not to buy fakes.
calculator is an electronic machine invented by modern people, which can carry out digital operation
modern electronic calculators are hand-held electronic machines that can carry out mathematical operations. They have integrated circuit chips, but their structure is much simpler than computers. They can be said to be the first generation of electronic computers (computers) with weak functions, but they are more convenient and cheap. They can be widely used in commercial transactions and are one of the necessary office supplies. In addition to displaying the calculation results, there are often overflow indication, error indication, etc. The calculator is powered by AC converter or battery, which can be recharged by AC converter or solar converter. In order to save electric energy, the calculators are all made of large scale integrated circuits in CMOS technology.
