about them comes out into the open.

The simplest way to write numbers in expanded form is to write them

sort of in English.

For 4,017, this becomes 4 thousands and 0 hundreds and 1 ten and 7

ones. This can be made to look like math by changing the words to math

symbols.The expanded form for 4,017, then, is:

4 x 1000 + 0 x 100 + 1 x 10 + 7 x 1

The expanded form shows what each digit is worth (for example, the 4

is worth 4 x 1000, which is the same as 4 thousands, which equals

4000).

Here is another example.

12,345 becomes 1 ten thousand and 2 thousands and 3 hundreds and 4 tens

and 5 ones. Changing the words to math symbols, 12,345 in expanded form

is:

1 x 10,000 + 2 x 1,000 + 3 x 100 + 4 x 10 + 5 x 1

Standard form is the reverse of expanded form. You begin with expanded

form and change it to the way we normally write numbers.

For example, 3 x 1,000 + 5 x 100 + 7 x 10 + 4 x 1 can be changed to

3 thousands and 5 hundreds and 7 tens and 4 ones. This becomes:

3000 + 500 + 70 + 4

Do the addition and you get 3574 (the standard form).

so, for your example it would be:

103,260,786

1 x 100,000,000 + 0 x 10,000,000 + 3 x 1, 000,000 + 2 x 100,000 + 6 x 10,000 + 0 x 1,000 + 7 x 100 + 8 x 10 + 6 x 1
