How to write a number in standard form

Each digit occupies a "slot" or place in the final number, and each place has a different value.

What Does Writing a Number in Standard Form Mean in Fourth Grade Math?

For example, the number is usually writtenYou use the same strategy to convert either to standard form. If the number is less than 1, count the numbers to the left of the decimal and multiply by 10 to a negative exponent of the number you counted.

Standard Form

When you have a decimal point, the slot just to the right of the decimal is the tenths slot, the slot to the right of that is the hundredths slot and so on. This pattern continues as you count up.

Numbers in Word Form Numbers in word form are written in a way that corresponds to how you would read the value of a word aloud. It has three digits, so you have a new slot or place value to deal with in a larger number. You can write that number in expanded form by multiplying each digit by its place value, then adding them together: If the numbers have different exponents, convert one of them to the exponent of the other.

Standard form

It equals the number of digits that follow the decimal. In standard form, this is 3. So you have one 10 and one 1. Note how as the decimal point moves, the exponent changes. The answer is Writing Numbers in Expanded Form The easiest way to visualize writing a number in expanded form is to see an example.

If the entire original number is greater than 1, count the numbers that appear to the right of this decimal. The value of the exponent indicates the magnitude of the number.

Standard, Expanded and Word Form

However, when starting to understand place value, being able to convert numbers to expanded form or back is a very useful skill. You simply add or subtract the strings of digits. You now have two digits in the number — the 1 and the 0.

How to Write Numbers in Standard Form

The number you find by counting is the exponent. The exponent equals the number of zeros plus the first digit in the number series. Put an addition sign between each component, and you have the number in expanded form: When you multiply numbers in standard form, you multiply the strings of numbers and add the exponents.

The final step is to connect the results with addition signs: Scientists handle very large numbers like this one, as well as very small numbers, by converting them to standard form, which is a decimal number followed by an exponent of Standard form is a way of writing down very large or very small numbers easily.

10 3 =so 4 × 10 3 = So can be written as 4 × 10³. This idea can be used to write even larger numbers down easily in standard form. Think of the standard form/scientific notation as shorthand writing, but for math instead of note-taking.
