Question

Multiply these binary numbers
100*011​

Answer 1

Answer:

(BIN)111 or (DEC)7

Step-by-step explanation:

First, let's convert these into decimal:

(binary) 100 → (decimal) 4

             011  →                3

Why? Because the nth digit from the right is 2^(n-1), so the third from right is 2^(3-1) = 4, and the middle one is 2^(2-1) = 2

Another way is:

  100

+011

  111

for example,

  110

+ 011

 1001
