Study Notes
Binary Numbering System
 Named after its base, which is 2
 Has 2 digits: 0 and 1
 Position values for a binary number are 2^x, where x is an exponent, and each position is twice the weight of the preceding one
Importance in Digital Electronics and Computing
 Used extensively in digital electronics and computing due to ease of representation using switches (0 = "off", 1 = "on")
 Allows for electronic storage and manipulation of data using digital circuits
Representation and Manipulation
 Used for representing and manipulating large binary numbers or expressing memory addresses in a compact format
 Computer programs and programming languages use number system concepts to perform arithmetic operations, store data, and communicate with hardware devices
Binary Arithmetic Operations

Addition
 0 + 0 = 0
 0 + 1 = 1
 1 + 0 = 1
 1 + 1 = 10 (write 0, carry 1 to the next higher bit)

Subtraction
 0  0 = 0
 1  0 = 1
 1  1 = 0
 0  1 = 1 with borrow from the next higher bit

Multiplication
 0 * 0 = 0
 0 * 1 = 0
 1 * 0 = 0
 1 * 1 = 1
 Multiply each digit of the second number by each digit of the first, then sum the results

Division
 Divide a dividend by a divisor to find a quotient and possibly a remainder
 Subtract in binary, bringing down the next digit
