BINARY NUMBER!

BINARY NUMBER!

come learn binary,the world of 0 and 1!

binary number's description

binary numbers are basically

in every single 0.01cm or lesser

in the computer. so it's basically

a kind of number that operates

a computer.

what are binary

How to write or understand a binary code?

before understanding a binary code,

let me tell you a thing.You know light

right?How many changes do it make?

Two:on and off.well , this two number:

0 and 1 is basically if on and off.

keep on understanding......

as the ex. I show you(--->),

in binary number , a place

is not timed by 10 by the

last place (ex. ones = 1 time

10 = tens time 10 = 100 = hundreds

time 10 = 100 = thousands),a binary

number is timed by 2.

keep on understanding......

And after you understand the places , now you can understand how to change a number into binary.First , choose a biggest place.(ex. 16) Then , list a chart.(ex. 16 8 4 2 1) Then , find the number you want to change(ex. 18). Then try to find how to group two number by the chart to get that number(ex. 18 = 16+2).Next , put 1s under the numbers that can add to the number you choose and put 0s under the ones that can not.(ex. 16 8 4 2 1)

--------------( 1 0 0 1 0)

finally , the binary number you got(ex. 10010)is the final answer.

Multiple Select

change this into a number:1001(four places)

• 1

• 4

• 2

• 9

how to make sure you are right?

just time the correspond number(up and down)and the sum will be the number before you've changed it into a binary number.(ex.8*0+4*1+2*1+1*0=6 , 6 = 0110).

ex(four places)

• 9 = 1001

• 6 = 0110

• 3 = 0011

• 2 = 0010

• 5 = 0101

Multiple Select

which one is wrong?

• 19 = 10011(5 places)

• 13 = 1101(4 places)

• 14 = 10111

• 1 = 0001(4places)

Text in binary.

easy to change text to binary , just find the number of the alphabet and change the num into binary.(ex:s=19=10011)

image in binary

it's easy to change image to binary,too!Because in every single image there is a thing called pixel , every single pixel have it's own colour.There are 3 things that makes a colour:R , G and B , each of those three value have it's own number , just change every single pixel's RGB value into a number then the image is changed into a binary image.

there are many kinds of it.

I will tell you in "BINARY NUMBER!II"

• 1

• 3

did you understand this kind of num?
