To write a number in expanded form, break apart a number, and write it as the sum of each place value. For example, 8324 = 8000 + 300 + 20 + 4. Decimals may also be expanded in a similar format: 0.239 = 0.2 + 0.03 + 0.009.
To write a number in expanded notation, rewrite it as a sum of its various place values. This shows the value of each digit in the number. For example, the number 123 can be written in expanded notation as 123 = 100 + 20 + 3.
In math, expanded form can refer to any type of expression, equation or notation that is completely broken down into its individual parts. Expanded form is commonly used in teaching students place value and factoring.
A number is in exponential form if it is given in the form A^b, where A is called the base and b is the power or exponent. To express a number written in exponential form in expanded form, the base number A is multiplied by itself the number of times shown by the power.
In mathematics, expanded form is a method of representing a number through an addition statement by totaling the values of its digits. For example, the number 3,745 can be written in expanded form as 3,000 + 700 + 40 + 5. A multiplication statement can also be used in expanded form.
The standard form of a decimal number places the decimal point after the first digit and then reflects the true size of the number by multiplying it by the appropriate power of 10. This form of a number is also known as its scientific notation form.
When discussing integers, standard form refers to an integer written as a number, while word form describes an integer written out as a word. Expanded form uses different numbers in an equation to express the integer.

The universe has been known to be expanding since 1929, when Edwin Hubble measured the speed at which distant galaxies appear to be receding from Earth's position in space. In the early 21st century, astronomers measured the rate of expansion and discovered that it is increasing.
A decimal number is written in expanded form by multiplying each individual number by the value of the decimal place that it occupies. Expanded form is rarely used, as both decimal form and mixed form are more convenient and practical forms of a non-whole number.
