SI202: Week 1

Converting a binary number to a decimal number. To convert a binary number to a decimal number, write the binary number as a sum of powers of 2. Example: Express the binary number 1011 as a decimal number. Note: We must be careful that the base is understood. When we say “11” above, we mean the number 11 in base 10, not the number 11 in base 2. ................
