Gain insights into essential number systems for computer scientists. Explore binary representation, and learn to represent and manipulate positive, negative, and fractional numbers stored in computers.

Get introduced to the number systems that are essential for computer scientists, and take a deep dive into binary representation. Learn how to represent and manipulate, positive, negative, and fractional numbers in binary, and learn how numbers are stored and represented in computers.

The only background this course requires is grade-school arithmetic. No programming knowledge is needed.

Number Systems For Computer Scientists

## Division method

For binary division, we will make use of the long division method we use with decimal numbers, which is:
>$A$ $\overline{)B}$ , where $A$ is the *divisor* and $B$ is the *dividend*.

There are some base rules in binary division:
- $1\div1 = 1$
- $0\div1 = 0$

Division by $0$ is undefined, so there are no rules utilizing it.
