The bits are determined by repeated division by 2 to yield either 0 or 1.

183/2 = 91 rem 1 => 1 (lowest bit) 2⁰
91/2 = 45 rem 1 => 1 (next higher bit) 2¹
45/2 = 22 rem 1 => 1 (next higher bit) 2²
22/2 = 11 rem 0 => 0 (next highrt bit) 2³
11/2 = 5 rem 1 => 1 (next higher bit) 2⁴
5/2 = 2 rem 1 => 1 (next higher bit) 2⁵
2/2 = 1 rem 0 => 0 (next higher bit) 2⁶
1/2 = 0 rem 1 => 1 (next higher bit) 2⁷
The next higher 24 bits have 0 in each bit.

For 32-bit system,
183 = 00000000 00000000 00000000 10110111 (with a space between bytes for readability)

What is the answer for this Evaluate 3|-3|.

Answer: 9

Concept:

Here, we need to know the idea of absolute value.

The absolute value of a number or integer is the actual distance of the integer from zero, in a number line.

There are no negatives in absolute value. So in practice "absolute value" means to remove any negative sign in front of a number, and to think of all numbers as positive.

Solve:

Given

3 |-3|

Expand absolute value sign, which means making [-3] positive

= 3 × (3)

Simplify by multiplication

= $\boxed{9}$
