Express a Small Number in Scientific Notation (Example), Pre-Algebra

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,...

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

This video contains additional scientific notation examples, continuing from the previous presentation. Viewers can see Sal work through several more problems using the techniques he has outlined throughout the pre-algebra video series.

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

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 handy video for an SAT prep or cumulative review.

Large numbers don't have to be a drag to work with. The video shows viewers how to estimate a large product of numbers. This involves first converting the numbers to scientific notation and then applying multiplication.

Practice converting a conventional number into scientific notation, and vice-versa. Using an applet, they perform the operations of multiplication and division on numbers expressed in scientific notation.

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 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.
