Answer 1

Answer:

Basically, for whole numbers, you start at the right most digit, the "ones" place. Each time you move left to a new digit, you are basically multiplying by ten. Let's look at 500: we start at the right most digit, a zero, so there are zero "ones". Then we move left, remembering to multiply our "place value" by ten. One times ten is ten, so we are in the "tens" place! In my example, 500 has a "tens place value" of zero. Finally, we move once more to the left. Ten times ten is one hundred, so we are in the "hundreds" place. 500 has five hundreds in its "hundreds place". Just remember that place values are like groups of that amount. Having five in the "ones place" really just represents 5, but having five in the "thousands place" represents five thousand!
