if you get into computers, you will have more variables that you can count in your code.

If you are the type that says when will I ever use this in real life, you would be surprised. Don't question why you need to learn algebra, just be glad you did down the road.

You actually use variables without even knowing it. For example, say you went to the store and wanted to get something for three friends. You only had 18 dollars and you wanted to get something for each of them that was the same price. You wouldn't probably jump to the conclusion that you needed to spend six dollars on each, but your brain is actually doing the variables. This is what you're acutally thinking in that split second

3x=18, where x= amount per friend, 3 = number of friends, and 18 = number of dollars. 3x divided by three equals 18 divided by 3. Cancel the three and x must equal 6! :)

As for using them in jobs, my boyfriend does research that requires him to do statistical math, which mainly involves things like variables. You should be glad that variables are often used in work, but calculus is not! :)
