Write in Scientific Notation

Young mathematicians learn how scientific notation is meant to save time. Part 10, out of a series of 15, asks scholars to recognize the correct use of scientific notation and finish by adding and subtracting numbers using...

Would you rather have a million dollars or 1 x 10^6 dollars? To find the answer to this question, class members first complete an assessment task converting numbers between decimal notation and scientific notation. They then take...

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...

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...

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.

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.

Numbers that are very large or very small are difficult to express in standard notation. Pupils learn how to convert between standard and scientific notation. They also multiply and divide the numbers 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...

Scientific notation is the focus of a five-question interactive. A model with movable points offers a visual reference to help solve true or false, multiple-choice, and fill in the blank questions. A discussion question challenges...
