The Battle for Ultimate Power

Explore scientific notation in this mathematics lesson. Young mathematicians explore multiple representations of large number in scientific notation through the use of models, visual representation and expanded form. The lesson provided...

Writing a number is all in the notation. The resource introduces the class to scientific notation. Pupils learn the process of taking a very large or small number in standard form and write it in scientific notation. To practice,...

Apply the concept of scientific notation to a word problem involving the rate of speed. Sal explains how to express the answer in scientific notation.

Explaining scientific notation is useful because "it allows us to write really large or really small numbers in ways that are easy for our brains to write down and understand," Sal proceeds to solve a few practice problems involving...

Sal uses a TI-85 graphing calculator to demonstrate how to check his work while he solves a complex word problem where he must use scientific notation to express his answer. This would be a very useful video for an SAT prep or cumulative...

Scientific notation is defined and used to express the number 0.0000000003457. This concept is not as clearly defined as it could be, and is probably not suitable for those who have not had prior experience with the concept.

The problems in this video contain additional examples of scientific notation, continued from the previous presentation. Viewers have the opportunity to see Sal work through several more problems using the same techniques he has been...

The instructor demonstrates how to convert a number written in scientific notation to a decimal number. An example is given for a number with a positive exponent, and an example is given for a number with a negative exponent.

Numbers with lots of zeros, lots and lots of zeros. Decimal points to the left and decimal points to the right. Now multiply these numbers. Daunting. There's a shorter way to do it, use scientific notation. The teacher demonstrates just...

The instructor demonstrates how to convert a number written in decimal form to scientific notation. An example is given for a number with a positive exponent and an example is given for a number with a negative exponent.
