Cheat Sheet
- Positional Weights in Binary -
Every binary digit represents a power of two, starting at 2^0 on the right (MIT OpenCourseWare). For example, 1101₂ = 1×2^3 + 1×2^2 + 0×2^1 + 1×2^0 = 13₀, so labeling each position's weight helps reinforce the concept when tackling binary number practice problems.
- Division-and-Remainder Method for Decimal to Binary -
The standard algorithm repeatedly divides the decimal number by 2 and records remainders (referenced by Khan Academy). Converting 13 to binary gives remainders 1,0,1,1 read bottom-up: 1101₂, so practice this step-by-step for binary conversion practice and fluency.
- Grouping for Hexadecimal Conversions -
Binary-to-hex conversion uses four-bit "nibbles" (IEEE Computer Society guideline), making it quick to translate between bases. For instance, 1010 1111₂ becomes AF₆ by converting each nibble: 1010 = A, 1111 = F, a trick useful in advanced binary to decimal practice.
- Understanding Two's Complement -
Two's complement is the standard for signed binary (Computer Systems: A Programmer's Perspective, CMU). Invert all bits of 00000101 and add 1 to represent -5 as 11111011, so practice flipping and adding for negative values in binary numbers practice problems.
- Mnemonic Tricks and the 128 - 64 - 32 - 16 - 8 - 4 - 2 - 1 Table -
Memorize the weights table "128 64 32 16 8 4 2 1" or use "Right To Left, Count Powers of Two" as a catchy phrase (University of Texas resource). Rehearsing this table speeds binary to decimal practice and decimal to binary practice, boosting speed and confidence.
