The digits in the ten-thousands place is 10,000 times the value of a digit, right? For example, 10,000 is 10,000 times 1, and one is a mere digit. The thousands place follows the same rule, with 1,000 being 1,000 times 1. Ergo, when compared, you could think of it as 10,000/1,000 = 10. We can think of this as a digit in the ten-thousands place is 10 times the value of the same digit in the thousands place.
-2 inches This is a simple average of 8 data points. All you need to do is add the value of all the data points together, then divide the sum by the number of data points. So (â’4 + â’6 + â’3 + â’1 + 0 + 2 + â’1 + â’3) / 8 = -16 / 8 = -2 S
