In order to be able to write a number in expanded form, you first need to understand how to find the value of a number. Value represents the worth of a number based on the place value it is in. If we want to find the expanded form of a number, we can write the value of each individual digit.
512,052
5 = 500,000
1 = 10,000
2 = 2,000
0 = 0 hundreds
3 = 30
2 = 2
After writing the values, we have to place the symbol for addition in the spaces between the numbers.
500,000 + 10,000 + 2,000 + 30 + 2
