In fact there is no such thing as too much practice.

To get the most out of these, you should work the problem out on your own and then check your answer by clicking on the link for the answer/discussion for that problem.

Since part of a number that is written in scientific notation is 10 raised to a power, when we multiply or divide these types of numbers we need to remember some of our exponent rules.

If you need to review your exponent rules, feel free to go to Tutorial 2: Integer Exponents.In this form, a is called the coefficient and b is the exponent.The coefficient is defined as an integer (except zero) to the left of a decimal point plus a mantissa.Like it or not, the best way to master these problems is to work through them. If the power on 10 is positive, you move the decimal place that many units to the right.If the power on 10 is negative, you move the decimal place that many units to the left.A manitssa is defined as the significant digits to the right of the decimal point.Here's an example of scientific notation with the important parts of the expression labeled: Look at all of those zeros.0.0167 = 1.67 x 10You may also need to convert numbers that are already represented in scientific notation or in their power of ten, to regular numbers. If the power is positive, shift decimal to the right If the power is negative, shift decimal point to the left The answer is in the negative because the decimal moved left. B The scientific notation is in the negative so we shift the decimal 2 places to the left. Introduction to Scientiic Notation: Learn the basic principles of scientific notation. Scientific Notation Generator: Javascript program will enable you to practice converting any number from basic notation to scientific notation.We would thus have 1.67 To complete the conversion of 29010 to scientific notation, we would get 2.91 x 10⁴ The 10 is raised to the power of 4, because there are 4 places counting from right to left.This scientific notation is positive because the decimal moved to the left. A The scientific notation is in the positive so we shift the decimal 6 places to the right.
