*These quizzes and practice tests on “Scientific Notation” are very helpful to check your knowledge on the subject. There are three difficulty levels.*

*These quizzes are good for “learning” as all questions contain “rules” or “clues”.*

*If you’ll take your time and learn to apply the “rule” to the corresponding question, you can “figure out” easily what the correct answers to the questions are.*

*You can take these quizzes as often as you want. You should repeat the quizzes until the moment you are able to apply all the rules on “Scientific Notation” to the questions.*

The Rules:

*The general form for numbers in scientific notation is: a x 10 ^{n} . Here n stands for an integer.*

*If we want to write a large number in this scientific notation, we first need to move our decimal point to a number that is between 1 & 10. *

*Because moving the decimal point is changing the value, we must apply multiplication by the 10th power which will result in a value equivalent to the original. *

*To determine or figure out the exponent, we only need to count the number of places that we moved our decimal sideways. This number is the exponent for the 10th power.*

*This process of moving the decimal and scientific notation is identical for very small numbers, between 0 and 1, but here, the decimal is moved to the right while our exponent will be negative.*

*The idea of “Scientific Notation” was created to assist scientists, mathematicians, and others when they’re working with or expressing very small or very large numbers.*

*Repeated practicing is the key to unlock your learning potential. When you navigate through the quizzes, you will improve your skills.*

*No problem if you take the quizzes as often as you like.*

*You may want to repeat the quizzes until you manage to apply all of the “Scientific Notation” rules to the questions.*

*The main goal of taking these quizzes is to help you explore a topic, start to think outside of the box, and learn the best way to apply your knowledge.*

*You are welcome to share these online quizzes with other students for additional practice to understand “Scientific Notation”.*
