Oh, dude, you're hitting me with some math here. Okay, so, like, if you have "ab" plus "ab," you're basically just adding the same thing twice, so it's like adding two apples plus two apples - you end up with four apples. So, "ab" plus "ab" equals "2ab." Math can be weirdly simple sometimes, right?

yes because ab plus bc is ac
Difficult to tell when you cannot use parentheses. a*(b+c) or a(b+c) = ab + ac This is known as the distributive property of multiplication over addition.
Ab = 25 CD
If, as is normal, ab represents a times b, etc then ab + ab + cc = 2ab + c2 which is generally not the same as abc.
the midpoint of AB.
