What is Binary
Digital electronics, especially in computing and
telecommunications, use the binary number system in
mathematics. The binary system only utilizes two digits,
0 and 1, in contrast to the decimal system, which
employs ten digits, (0 through 9).
Binary and Denary
There are two different numerical systems
for representing numbers: binary and
denary (decimal). The only two digits used
in binary, a base-2 system, are 0 and 1, and
the position of each digit represents a
power of two."
It is frequently used in computers and
digital electronics. Ten digits, 0 through 9,
are used in Denary, a base-10 system. The
position of each digit represents a power of
10. It is the main number system that is
utilized in both mathematics and daily life.
How to turn binary to denary
Let’s convert the binary number 1101 into denary

Start from the
rightmost digit
(the least
significant bit)
multiply the
rightmost
digit by 2
raised to the
power of 0
Move to the left
and multiply the
next digit by 2
raised to the
power of 1.
Repeat this
process until you
reach the leftmost
digit.
If you follow all the
steps, the answer is
13.
Logic gates
Logic gates are fundamental building blocks of digital
circuits. They process binary information (0s and 1s)
based on Boolean algebra. Common types include AND,
OR, and NOT gates, each performing specific logical
operations.
NOT GATE
AND GATE
OR GATE
Output is the opposite of
the input.
Output is true only if all
inputs are true.
Output is true if at least
one input is true.
Remote learning as
the new normal
IT'S IMPORTANT RIGHT NOW
BUT IS IT THE FUTURE?
Remote learning technology has been crucial to
education right now, and it will likely be as critical in
the future as schools determine the best way they
can move forward. Schools can adopt or offer a
combination of remote and in-person learning.
