Have you ever tried to guess how many pieces of candy there are in a jar? Or tackled a mindbender like: _How many piano tuners are there in Chicago?" Physicist Enrico Fermi was very good at problems like these -- learn how he used the...

Paul Andersen explains pH as the power of hydrogen. He explains how increases in the hydronium ion (or hydrogen ion) concentration can lower the pH and create acids. He also explains how the reverse is true. An analysis of a strong...

In this shorts video we will discuss scientific notation & standard form. We will be given a value written in scientific notation. We will understand that it is in scientific notation since there is one significant digit to the left of...

In this math video we will find the product of values in scientific notation. We will understand that scientific notation is a factor multiplied by a power of ten. We will write a value from scientific notation to standard form with a...

A video entitled "Add/Subtract Scientific Notation" which shows how exponents much match in order to add numbers in scientific notation.
