Example 5: Rewrite the given decimal number 0.00000000086 in scientific notation. Maybe you can predict that since the given decimal number is between 0 and 1, we should have a scientific notation with a negative power. First, identify the initial decimal point and where it is going.

If we moved the decimal point to the left in step one, then the number we raise 10 to will be positive, and if we moved the decimal point to the right in step one, then the number we raise 10 to will be negative. Write the number using scientific notation with the information obtained in steps one and two.

Naming very large numbers is relatively easy. There are two main ways of naming a number: scientific notation and naming by grouping. For example, the number 500 000 000 000 000 000 000 can be called 5 x 10 20 in scientific notation since there are 20 zeros behind the 5. If the number is named by grouping, it is five hundred quintillion or 500 trillion ().

You would therefore write 6 million using scientific notation as: six multiplication 10 super six. Similarly, if the example had been six and a half million (6 500 000), this can be written in scientific notation as: 6.5 multiplication one 000 000 or 6.5 multiplication 10 super six in scientific notation.

Scientific notation is, quite simply put, a way of writing really large numbers in a smaller amount of space. It is a notation born out of laziness, if you will. The idea is that instead of writing the whole number out, one will simply write a multiplication problem, and have the core number (that is, the number appearing first) in the form of a single digit.

In writing scientific notations, the convention is to have only one digit before the decimal point. Numbers that are greater than one have a positive power in scientific notation. If the decimal point is moved to the left n places, the power (n) of 10 is positive. Numbers that are less than one have a negative power in scientific notation.

Perhaps, you have reached us looking for the answer to a question like: How to write 2.3 million in words. This number to words converter can also be useful for foreign students of English (ESL) who need to learn both how to write and how to pronounce the cardinal and ordinal numbers.

The rule for writing a number in scientific notation is to write it the product of two numbers. The first number, called the mantissa, must have its absolute value between 1 and 10, and the second number must be written as 10 raised to an integer power.

To write a number in scientific notation: Put the decimal after the first digit and drop the zeroes. In the number 123,000,000,000 The coefficient will be 1.23 To find the exponent count the number of places from the decimal to the end of the number.

When astronomers are doing calculations with such large numbers, it can become quite difficult to keep track of all the zeros. There is another way to write such large numbers that makes working with them much easier. This method is known as scientific notation. It is a special notation that helps us work with scientific numbers.

Scientific notation allows us to reduce the number of zeros that we see while still keeping track of them for us. For example the age of the Earth (see above) can be written as 4.6 X 109 years. This means that this number has 9 places after the decimal place - filled with zeros unless a number comes after the decimal when writing scientific notation.
