Answers are provided in three formats: You can also do operations on whole numbers, integers, and decimal numbers and get answers in scientific notation.

In science, we deal with numbers that are sometimes extremely large or extremely small. It helps to have a calculator around when doing math with such large numbers but you have to know how to use one.

There are ,,,, molecules in 18 grams of water. A shorter way of writing the same number is by using exponential notation to show all those zeros as a number to the power of ten: Such a number can be read "Six point zero two times ten to the twenty third.

Such a number can be read "Five point seven times ten to the minus nine.

Well, it's all in how you move the decimal point. Writingfor example, means that you are writing a one and then moving the decimal point four places.

Since the exponent the 4 is a positive number, we move the decimal place to the right. The animation below shows how it is done: Notice that the animation starts by reminding us that when we write "1", we are really writing "1. At the end of the animation, the decimal point is in its new place, but again, we do not write it.

Notice, also that there is a total of four zeroes. This is one way of checking if you did it correctly. Now let's try the opposite. What if the exponent is a negative number? With the numberthe technique starts out the same - we write a number 1, remembering that there is a decimal point after it.

But then instead of moving the decimal point to the right, we move it to the left.

To remember which way to move left or rightremember that negative exponents like -4 in the example represent very small numbers - numbers that are less than one.

As a result, they will always start with zero. Positive exponents like 4 in the examplegive numbers bigger than one. On scientific calculators, it is sometimes a bit of a trick to type these numbers in.

To typeone way of doing it is to type ten: Then use the xy button and type 4 The result should be ten thousand: But there is a quicker way, using a special button which has been designed especially for exponential notation.

Can't find this button on your calculator? See the next box. You should get this: If your calculator works like this, you can skip the next box. Let's see what happens when we try ten.View and Download Texas Instruments TIX - IIS Scientific Calculator teachers manual online. Scientific calculator.
