What number do the blue squares below represent?
In our number system, we read from right to left for place values. The rightmost position is always the ones place, so in 89, the digit 9 is in the ones place.
In 90, the ones digit would be 0 (the rightmost digit), and the tens digit would be 9. Remember: position matters more than the actual digit!
Think of place values like house addresses: ones place is house #1 (rightmost), tens place is house #2 (second from right). Always start counting positions from the right!
Yes! Point to each digit starting from the right and say: "ones, tens, hundreds..." The first digit you point to (rightmost) is always the ones digit.
Same rule applies! Count from right: 9 (ones), 8 (tens), 7 (hundreds). The rightmost digit is always the ones place, no matter how big the number gets.
