Practice focus

Binary, decimal, and hexadecimal are three ways to write the same quantity. Decimal is base 10, binary is base 2, and hexadecimal is base 16, and every number has one correct form in each. Being able to translate freely among the three is a core skill for reading how computers store numbers.

Grade placement is a planning guide for choosing practice. The registry records standard-code mappings as unreviewed, so these pages are not a claim of alignment with a national standard.
