### 1. Is this a positive or a negative number?

#### 0110 1101 is the binary representation of a positive integer, on 8 bits.

#### In a signed binary, the first bit (the leftmost) is reserved for the sign,

#### 1 = negative, 0 = positive. This bit does not count when calculating the absolute value.

### 2. Construct the unsigned binary number.

#### Exclude the first bit (the leftmost), that is reserved for the sign:

#### 0110 1101 = 110 1101

### 3. Map the unsigned binary number's digits versus the corresponding powers of 2 that their place value represent:

2^{6}

1 2^{5}

1 2^{4}

0 2^{3}

1 2^{2}

1 2^{1}

0 2^{0}
