trying to figure out how to vlaue the digits in numbers
To figure out the value you have to look at all of the numbers from right to left. You start with the ones place and get prgressively bigger going up by a multiple of 10 each time. So you have the ones, tens, hundreds, thousands, ten thousands, etc. In the number in your example, you have 3 ones, 4 tens (or 40), 1 hundred or (100), 0 thousands, and 5 ten thousands (50, 000). You can write the number in expanded form to help you figure out the value. 50,000 + 100 + 40 +3.
