Study Notes
Number Systems
- A number system is a set of symbols and rules for representing numbers.
- A number system is formed by a set of elements and symbols.
- It's a way to represent quantities using symbols.
- Positional notation relies on the position of a digit to represent its value; the value of the digit changes based on its position.
- The system of numbers may be additive (positive) or subtractive (negative).
- Each symbol within a number has a defined value based on its position.
- The base of a number system specifies how many symbols are available to represent numbers.
- Examples include decimal (base 10), binary (base 2), octal (base 8), hexadecimal (base 16).
Converting Bases
- Converting numbers between bases involves understanding the place value system.
- Converting a base-b number to base-10. For example:
- Calculate the place value for each digit in a number in a base-b system
- Multiply each digit by its corresponding place value
- Sum up the values to get the equivalent number in the base-10 system
- Converting a base-10 to a base-b number. For example:
- Repeatedly divide the number by the base-b
- Collect the remainder in the reverse order.
- The remainders represent the digits in the base-b system.
Examples and Exercises
-
Example: Converting the decimal number 26 to binary:
- 26 ÷ 2 = 13, remainder 0
- 13 ÷ 2 = 6, remainder 1
- 6 ÷ 2 = 3, remainder 0
- 3 ÷ 2 = 1, remainder 1
- 1 ÷ 2 = 0, remainder 1
- Reverse remainders are 11010, therefore 2610 = 110102
-
Example: Converting the binary number 11010 to decimal:
- The binary number 110102, has the following place values:
- 24, 23, 22, 21, 20
- Calculate the result in base-10
- 1*(2^4) + 1*(2^3) + 0*(2^2) + 1*(2^1) + 0*(2^0) = 16+8+0+2+0 = 26
-
Tables and examples illustrate conversion processes from different bases to decimal and vice versa.
