 WONDER what are the components inside a calculator

 Hi

     I act as the monitor of my system.I can display 10 characters at a time.Usually liquid crystals are incorporated inside.My display composed of 5 layers.Wonder why you see the results in decimal form?(My system has an encoder and decoder unit

converts the numbers and functions into binary form whereas the decoder converts the processed binary numbers into decimal form)

 Hello
          I'm the vital part of my system.Whenever you do a calculation it goes inside my system.My heart contains scanning unit , encode unit, memory...etc.When you turn on my system,it scans the keypad waiting to pick up an electrical signal when a key is pressed.All the arithmetic operations are stored inside my memory.you can term it as ROM.

 Hello friends

                     We altogether perform the switching function.My circuit board contains button contacts which are activated by button switches.When you press a number the button contacts will get activated by means of button switches

Hello

     I act as auxiliary power supply in my system.I got connected in parallel with the normal power unit,which is usually a battery of 1.5v . I cannot provide as much as energy as you are thinking .I deal with low voltage.I mean i give more energy when sun is too bright out there.

Hi there

I have the habit of doing almost all the functions that a calculator can do.All the mathematics,electronics,electrical..etc are carried out here.Therefor it's better to call me the "NUCLEUS"

So NEVER WONDER who's doing the mathematics.
