Question

Multiply 7x13 in binary.

Answer 1

Answer:

1011011

Step-by-step explanation:

The binary multiplication is pretty much like the decimal one, we have just to remember that in the binary system 1+1 = 10.

First, convert 7 and 13 to binary

7 = 111

13 = 1101

now multiply with the same rules as in decimal

        1101x

          111

   --------------

         1101+

       1101  +

     1101

    1111

 -------------

   1011011

The last row of digits are the carry bits.

So 7*13 = 1101*111(binary) = 1011011 (binary)
