📚 Topic Summary
Binary addition is the foundation of arithmetic in computer systems. Unlike decimal addition, which uses base-10 (0-9), binary addition uses base-2 (0 and 1). When adding binary numbers, you follow similar rules to decimal addition, but with only two digits. The key concept is that 1 + 1 equals 10 in binary, where 0 is the sum and 1 is the carry-over. This carry-over is then added to the next column. Understanding this process is crucial for grasping how computers perform calculations at their core.
Mastering binary addition is a stepping stone to more complex concepts in computer science, like logic gates and data representation. Practice makes perfect, so work through the exercises to solidify your understanding. Remember that each position in a binary number represents a power of 2 (e.g., $2^0, 2^1, 2^2,$ etc.), which is how computers translate binary into decimal values.
