Number systems like binary (base 2), octal (base 8), and hexadecimal (base 16) appear in computing, while decimal is base 10. To convert a decimal integer to binary, repeatedly divide by 2, gathering remainders. For example, 13 in binary is 1101. Reversely, sum place values 1×2³+1×2²+0×2¹+1×2⁰=8+4+0+1=13. Conversions among bases are vital in digital electronics, programming (memory addresses), or cryptographic systems. Mastering them fosters agility with computational tasks and fosters deeper understanding of how digital systems store and process numbers.
