Thread: 2 number word problem calculator

For 2011, I'm going to try to build some common word problems as well besides the mortgage calculator. Any ideas would be great. I just finished a 2 number word problem calculator that handles word problems that follow the following question format:

* Two numbers have a sum of 70 and a product of 1189 What are the numbers?
* Two numbers have a sum of 70. Their difference 32
* Two integers have a sum of 437 and a difference of 313, what are they?

These require real number solutions. I will try and expand on this in the future. Let me know if you want fixes or enhancements.

One of them results in a straight math calculation, while the other links to our quadratic calculator.

You can enter these on the search engine anywhere on the site. The link above is straight to the lesson.

Tell me more about your mortgage calculator, what do you hope to achieve?

The mortgage calculator is here:
Mortgage Payment Calculator

I created that over a year ago to demonstrate mortgage math for some friends and colleagues who were more than curious about their car/house payment and the actual math behind it.

I created the shortcut a few weeks ago so that people could click and go straight from the search engine if they had a word problem or a question.

For folks who are in Finance Math, I think it is a good intro lesson to basic annuities and present values. I added the amortization table and principal/interest early last year as well to show how much principal/interest/payoff one has left.

I grew up with Kellison's Theory of Interest book which was really helpful, and I crafted most of the Finance page straight from that book.
