"The decimal value of 54 (base 10) converted to binary is 110110 (base 2).

A binary number is a number expressed in the base-2 numeral system or binary numeral system.

To convert a decimal number to binary, we can use the following steps:

Divide the decimal number by 2 and record the remainder (0 or 1) as the least significant bit (LSB) of the binary number.

Repeat the process with the quotient until it becomes 0.

Write the remainders in reverse order as the binary number.

For example, to convert 54 to binary, we can do:

54 / 2 = 27, remainder 0 -> LSB = 0 27 / 2 = 13, remainder 1 -> next bit = 1 13 / 2 = 6, remainder 1 -> next bit = 1 6 / 2 = 3, remainder 0 -> next bit = 0 3 / 2 = 1, remainder 1 -> next bit = 1 1 / 2 = 0, remainder 1 -> MSB = 1

So, the binary number is 110110.

To convert a binary number to 2's complement, we can use the following steps:

If the binary number is positive (MSB = 0), then the 2's complement is the same as the binary number.

If the binary number is negative (MSB = 1), then the 2's complement is obtained by flipping all the bits and adding 1.

For example, to convert 110110 to 2's complement, we can do:

Since the MSB is 1, the binary number is negative.

To flip all the bits, we change 0 to 1 and 1 to 0, so we get 001001.

To add 1, we start from the LSB and carry over if needed, so we get 001010.

So, the 2's complement is 001010.

Note: The 2's complement is a way of representing negative numbers in binary. It has the advantage of allowing addition and subtraction to be performed using the same hardware. The 2's complement of a binary number is the inverse of its 1's complement, which is obtained by flipping all the bits. The 2's complement of a binary number can also be interpreted as the negative of its 1's complement. For example, the 1's complement of 110110 is 001001, and the 2's complement of 110110 is 001010, which is also -001001."
