Converting Decimal to Binary:
- To convert a decimal number to binary, you can use the division method.
- Start by dividing the decimal number by 2 and write down the remainder.
- Continue dividing the quotient by 2 until you reach a quotient of 0.
- Write down the remainders in reverse order to get the binary equivalent.
- For example, to convert decimal 13 to binary:
- 13 divided by 2 is 6 with a remainder of 1
- 6 divided by 2 is 3 with a remainder of 0
- 3 divided by 2 is 1 with a remainder of 1
- 1 divided by 2 is 0 with a remainder of 1
- Therefore, 13 in binary is 1101.

Converting Binary to Decimal:
- Converting binary to decimal involves multiplying each digit of the binary number by 2 raised to the power of its position, starting from 0.
- Add all the results together to get the decimal equivalent.
- For example, to convert binary 1101 to decimal:
- (1 * 2^3) + (1 * 2^2) + (0 * 2^1) + (1 * 2^0)
- = (1 * 8) + (1 * 4) + (0 * 2) + (1 * 1)
- = 8 + 4 + 0 + 1
- = 13
- Therefore, binary 1101 is equivalent to decimal 13.
