Part of Lesson Plan: B7- When Does 3 and 6 = 7- How Computers Calculate

Activity Overview / Details

At the root of their logic, computers add without the ability to carry numbers to the next place. So if I were to ADD the numbers three and six, for example, it would look like this in binary:

          0 1 1  (three in binary)
AND   1 1 0  (six in binary)
           1 1 1  (seven in binary)

So we can see that using Boolean Algebra, 3 AND 6 equal 7 Try telling your algebra teacher that!
