see how they are represented in a computer. In Chapter 4 we see how to
control electrical signals that represent binary values. And in Chapter 7 we
see how binary numbers are used to represent program commands that the
computer executes.
Summary
Numbers are written using positional notation, in which the digits are
arranged in succession, the position of each digit has a place value, and the
number is equal to the sum of the products of each digit by its place value.
The place values are powers of the base of the number system. Thus, in the
decimal number system, the place values are powers of 10; in the binary
number system, the place values are powers of 2.
Arithmetic can be performed on numbers in any base represented in
positional notation. The same number facts apply to other bases as they do
to base 10. Adding 1 to the largest digit in the base causes a carry into the
next position.
Base 2, base 8, and base 16 are all related because the bases are powers of
