Cheat Sheet
- Binary Place Values and Powers of Two -
Each bit in a binary number represents a power of two (2^0, 2^1, 2^2, …), forming the foundation of all binary questions (MIT OpenCourseWare). For example, 10110₂ equals 1×2❴ + 0×2³ + 1×2² + 1×2¹ + 0×2❰ = 22. Use the mantra "double and add" as you move left across bits to streamline your binary practice.
- Decimal-to-Binary Conversion Technique -
The classic division-by-2 method helps convert decimals into binary by recording remainders in reverse order (University of Michigan CS resources). For instance, converting 30 to binary: 30 ÷ 2 = 15 R0, 15 ÷ 2 = 7 R1, … yields 11110₂. Practicing this algorithm makes every binary exam feel like a breeze.
- Binary Addition and Carry Rules -
Binary addition follows simple rules: 0+0=0, 0+1=1, 1+1=10 (carry 1), and 1+1+1=11 (carry 1 with sum 1) (Khan Academy). For example, adding 0111₂ + 0101₂ gives 1100₂ after handling carries. Mastering these steps ensures smooth sailing on any binary quiz or binary test.
- Two's Complement for Signed Numbers -
Two's complement is the industry standard for representing negative values by inverting all bits and adding one (IEEE standards). For example, to encode - 5 in 8 bits: start with 00000101, invert to 11111010, then add 1 to get 11111011₂. This method simplifies arithmetic and is critical for digital systems and binary practice problems.
- Essential Bitwise Operations -
Bitwise AND, OR, XOR, and shifts manipulate individual bits directly (Stanford CS Lecture Notes). For instance, 1011₂ AND 1101₂ = 1001₂, highlighting common patterns in logic gates. Regularly testing these operations in your binary questions toolkit builds confidence for real-world coding and system design.
