Default Sample problem

If you have a mortgage payment on a house that costs $100,000 and you have a choice of paying
1) $421.60 per month for 30 years or a total of $151,777.45
2) $554.60 per month for 20 years or a total of $133,103.42

which mortgage is the better deal? Which has the higher interest rate?

If you feel like option 2 is too expensive, and you take option 1, how much money will you still owe on the mortgage after 20 years.

Only 3 eggs for deviled eggs? Must be watching your cholesterol.

Just because they don't call the unknown x doesn't mean you aren't doing algebra.

Because I am good at math. Other people are good at other things.

It isn't doing then in your head or not that is important but rather knowing how to do them at all. That is why we teach problem solving with math aka algebra.

I'm not good at algebra. I had a brain injury at birth.

I guess I'm doomed to be a failure.

Why do them in your head? That's why we have pen and paper, calculators, etc.

The thing you need to master is algebraic thinking. That how you figure out how you need to solve the problem.

You are on the internet. You are using English, grammar and punctuation. Your brain seems to be working just fine. There are no special "algebra brains." Don't make excuses.

I was a math tutor in college. The biggest hindrance to people learning algebra, calculus, etc is that they are intimidated by math. They use negative self talk to talk themselves out of learning.

Instead of thinking "I'm doomed," how about thinking "regular people do this everyday. I'll work hard and I'll eventually get it too."

A positive attitude and patience will take you far.
