A List of Lessons in the Notation Curriculum
What Is Notation?
Some numbers can be very large...
Some numbers can be very small...
Writing out so many numerals can be very time consuming, especially if they are part of a long calculation.
Scientific and Engineering notation is a way of writing very large or very small numbers in a standard (shorter!) way.
| 12,300,000,000 = 1.23 × 1010 | Scientific notation |
| 0.0000000123 = 12.3 × 10−9 | Engineering notation |
What Is Scientific Notation?
Scientific notation writes a number as a number between 1 and 10 multiplied by a power of 10. The number below is written in scientific notation. It is said as "1.2 times 10 to the 3".
Dictionary Definition
The Oxford English Dictionary defines scientific notation as "a system of representing some given number as a product of a number with an absolute value between 1 and 10 and a power of 10 (as 2 × 102 for 200)."What Is Engineering Notation?
Engineering notation writes a number as a number between 1 and 1,000 multiplied by a power of 10 that has an exponent that is a multiple of 3. The number below is written in engineering notation. It is said as "123.4 times 10 to the 3".
- 123.4 is between 1 and 1,000.
- 103 is a power of 10. The exponent is 3, which is a multiple of 3. 106, 109 and 1012 also have exponents that are multiples of 3.

Powers of 10
A power of 10 is 10 raised to a exponent, which tells you how many times 10 is multiplied by itself. Here is an example of a power of 10:
An exponent of 2 means that 10 is multiplied by itself 2 times.
