The binary numeral system is a way to write numbers using only two digits: 0 and 1. In binary, each digit's place value is twice as much as that of the next digit to the right (since each digit holds two values).

Here is an example of a binary number and how it reads in Arabic numbers: 10110011

The place value of the last 1 (rightmost position) is 1.

The place value of the 1 before that is 2.

The place value of the 0 before that is 4.

The place value of the 0 before that is 8.

The place value of the 1 before that is 16.

The place value of the 1 before that is 32.

The place value of the 0 before that is 64.

The place value of the 1 before that is 128.

Adding together all the place values that have 1s, it would be 1+2+16+32+128 = 179.
