They could go all, the, way...to a deeper understanding of integers with this fun math game. Using the included printable materials, young mathematicians practice adding integers and calculating absolute values as they compete in a game...

It's more than just numbers on a line, its an organizational, mental math machine to help learners understand the value of numbers. The tool is handy when introducing positive and negative integers to see their values and relationships....

To subtract two polynomials Sal demonstrates that you add the opposite of the second term, and then combine like terms to solve. How do you find an opposite term? Simply multiply the polynomial by -1. This video is very clearly explained...

In order to subtract mixed numbers, sometimes one may need to determine the least common multiple in order to find a common denominator. This is just what Sal does in this presentation. First, he shows how to find a common denominator...
