Addition with Variables
Date: 4/16/96 at 11:16:30 From: "Matthew Auman Jennings" Subject: algebra I had a difficulty answering the following question on last night's homework assignment. I was wondering if you could help me with it. 3a+a Matt

Does it help to rewrite your question as (3 * number) + number? Then we see that we get 4 * number. So the answer to your question is 4a. I hope that this helps. Let us know if you need a better explanation. -Doctor Jodi, The Math Forum
