1100011

the answer is 1111.

11–13 = 11 + (-13) = 00001011 + 11110011 = 11111110. A 1 at the left most bit signifies negative number. Since this is in 2’s complement, we subtract 1 from it to get the 1’s complement notation of 11111101. Flipping the bits we get 00000010 or 2, meaning our result is -2 in 2’s complement notation.

For binary multiplication, we follow the same process as multiplying two decimal numbers where we multiply each digit of the second number by the first whole number, then we just need to add them, switching each resulting multiplication one digit to the left.

Multiplying by 2 is equivalent to a shift left by 1 bit, division is a right shift. similarly it is the same trivial to multiply and divide by any power of 2.

When we divide a base-2 number by 2 we also just shift them right. So shifting right 13 means dividing by 2. So, you lose the last bit (the 1) that means you always round down, like 12/2=6. That is even, so our binary result is 01.

Therefore, range of 5 bit unsigned binary number is from 0 to (25-1) which is equal from minimum value 0 (i.e., 00000) to maximum value 31 (i.e., 11111). 2. Signed Numbers: For example, in representation of negative decimal numbers, we need to put negative symbol in front of given decimal number.

ADVANTAGE of signed magnitude: You can determine whether a number is negative or non negative simply by testing the most significant bit. DISADVANTAGES of signed magnitude: One of the bit patterns is wasted. Addition doesn’t work the way we want it to.

To multiply a number, a binary shift moves all the digits in the binary number along to the left and fills the gaps after the shift with 0: to multiply by two, all digits shift one place to the left.

Left Shifts When shifting left, the most-significant bit is lost, and a 0 bit is inserted on the other end. The left shift operator is usually written as “<<“.

A right arithmetic shift of a binary number by 1. The empty position in the most significant bit is filled with a copy of the original MSB. A left arithmetic shift of a binary number by 1. The empty position in the least significant bit is filled with a zero.

1000, 1001, 1010, 1011, 1100, 1101, 1110, 1111 In the binary system, each digit represents an increasing power of 2, with the rightmost digit representing 20, the next representing 21, then 22, and so on.

When you get to “two”, you find that there is no single solitary digit that stands for “two” in base-two math. Instead, you put a “1” in the twos column and a “0” in the units column, indicating “1 two and 0 ones”. The base-ten “two” (210) is written in binary as 102.

0.75=12+14=1×121+1×122. The decimal number 0.75 is written as 0.11 in binary.

Let’s look at binary codes for all letters of the English alphabet to give you an idea of how to write functions in code: A: 01000001. B: 01000010. C: 01000011.

For example, if 1210 is a decimal number then its equivalent binary number is 11002….Decimal to Binary Table.

The binary number of 42 is 101010 .

So, 1001000 is the binary equivalent of decimal number 72 (Answer).
