Combining+like+terms

__Combining Like Terms:__
by Dominique:

Combining like terms is when you add terms that are the same to simplify the problem. For example: 2a+4a+5a+1 You would add 2a, 4a, and 5a because they all have the same variable which is "a". The problem would simply break down to be: 11a+1 Which is a much smaller the beginning problem. This link below is a good site that has examples of combining like term:

**More examples:**
x+2x+3b+b = 3x+4b 7u+4u-4b = 11u-4b 8d-d-7h-h = 7d-8h
