For extremely large values of two. http://www.thinkgeek.com/tshirts/generic/60f5/ 1. Let a = b. 2. a*a = b * b 3. a * a - b * b = 0 Since a = b, substitute to get: 4. a * a - a * b = 0 5. a * (a - b) = 0 = (a + b) * (a - b) 6. a = a + b 7. a = 2 * a 8. 1 = 2 So, 2 + 2 = 1 + 1 = 2. (Note: this doesn't hold; step 5 to 6 is invalid.)

Never. Two of something plus of two of something will always equal a total of four. That's the great thing about Mathematical truths.

2 + 2 = 4 There are no exceptions.

When you use a base that makes it not four. Saw you got DRd for a good trick question, so +4

A real life example for the layman (like myself) would be if one of the first two is the same as one of the second two! For example, you have an apple, an orange and a pear. The apple and the pear make up two items of fruit. The apple and the orange make up two items of fruit. But if you combine the two you still only have 3 bits of fruit as you only have one of each of the apple, pear and orange.
