Can someone help me with this?
The math problem is this:
Find values of a and b for which the statement is true:
| a + b | < | a | + | b |
Thank u!
It's pretty well known that |a + b| ≤ |a| + |b| for all real number a and b. This is known as the triangle inequality (you can search for it on google). So the only question you have to answer is when is it that:
|a + b| ≠ |a| + |b|
The answer to this question is the same as the answer to yours.
"In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..."
