The binary number system uses only two digits, 0 and 1, to represent all numbers. It was invented by an Indian scholar named Pingala in the 2nd or 5th century BCE and is used internally by modern computers. To convert a base-10 number to binary, you divide the number by 2 and write down the remainders until reaching zero, then write the binary number from the remainders from bottom to top.

2. What is Binary
Number System
Binary number system is a
system that only uses two
numbers, 0 and 1. It is
similar to morse code but is
used for numbers and
computers.

3. Who invented the
Binary Number
System/ Binary
Code?
Binary number system was invented
by an Indian Scholar named
Pingala. He lived in the 2nd/5th
BCE ( the dates of hi lifetime are not
really known). Similar systems have
been used traditional African
divination systems, but they were
not the binary number system we
know today.

4. How is it used?
Binary code is used internally by all
modern computers. The first computer
to use the binary number system was
invented in 1937 by George Stibitz. It
was also used to send information over
long distances. It was then adapted to
be used by computers so that they could
understand information that is being
inserted.

5. How do you convert to Binary
number system from the base-10
(10 digits) number system?
To convert: Divide the number in Base-10 by 2 until you get
to zero. Write down the remainders. then you would write
the binary number from the remainders, bottom to top. So,
say 6 is the number we want to convert to binary. We would
divide it by 2 to get 3. The remainder is 0. Then, we would
divide 3 by 2. The remainder is 1. Last, we would divide 1 by
2. The remainder is 1. Then, we take the remainders from
top to bottom. 6 in binary is 110.
For example: 6/2=3...0
3/2=1...1
1/2=0 ...1
