Expanded form is when you separate out all the digits to show how the number comes together. For example, "7843" when converted to expanded form is 7000 + 800 + 40 + 3. 7 is in the thousands place so it becomes 7000, 8 is in the hundreds place so it becomes 800, 4 is in the tens place so it becomes 40, 3 is in the ones place so it stays as 3.

For decimals you do pretty much the same thing so here's a decimal example: "75.34". This becomes 70 + 5 + 0.3 + 0.04!

Expanded form refers to expanding a number to show how the values in each place add together to make the final number. For example, for the number 123, it can be expanded to show the number of hundreds + the number of tens + the number of ones: 100 + 20 + 3

...Expanded also known as expanded notation means u split up a number as the sum of its powers of 10

eg 423.91

(4 x 10^2) + ( 2 x 10^1) + (3 x 10^0) +(9 x 10^-1) + 91 x 10^-2)

It's what the equation was before you foil it. You can figure out the expanded form by unfoiling. Kahnacademy has some videos on it. You should check them out.

...Expanded form is math means breaking down the numbers, for example 4231 is four thousand, two hundred and thirty one (4000, 200, 30, 1)

...25, 827= 20,000+5000+800+20+7

In the expanded form, the value of each digit is clearly shown.
