Explanation

Number bases: decimal (base 10) uses 0-9. Binary (base 2) uses 0,1 – used in computers. Octal (base 8) uses 0-7. Hexadecimal (base 16) uses 0-9 and A-F.

Converting: divide by new base, remainders are digits (read upward). 25 in binary: 25÷2=12r1, 12÷2=6r0, 6÷2=3r0, 3÷2=1r1, 1÷2=0r1. So 25₁₀ = 11001₂.

Converting to decimal: multiply each digit by place value and sum. 11001₂ = 1×16 + 1×8 + 0×4 + 0×2 + 1×1 = 25₁₀. Computers use binary; humans prefer decimal.
