  How binary numbers are multiplied ?
  It's pretty simple
  Check this image :
  
  
  Two 4-bit binary numbers are multiplied here :
  A containing A0,A1,A2 & A3
  B containing B0,B1,B2 & B3
  
  Now I guess from image you got the idea that
  - First A3,A2,A1 & A0 is multiplied by B0
  - In second step, one space left is shifted & then A3,A2,A1 & A0 multiplied with B1
  - In third step, one more space to left is shifted addition to above (i.e. 2 space now) & A3,A2,A1 & A0 multiply with B2
  - Do same with B3.
  - Add it all & get the answer.
  
  Binary multiplication rules :
  0x0=0
  0x1=0
  1x0=0
  1x1=1
  
  Note : I guess from the image you can get the idea. 😀
