Learn to recognise, read and write and write up to 9-digit numbers.
You Know That:
- Adding 1 to the greatest 1-digit number gives the smallest 2-digit number.
That is, 9+1 is 10.(Ten) - Adding 1 to the greatest 2-digit number gives the smallest 3-digit number.
That is, 99+1 is 100.(One Hundred) - Adding 1 to the greatest 3-digit number gives the smallest 4-digit number.
That is, 999+1 is 1000.(One Thousand) - Adding 1 to the greatest 4-digit number gives the smallest 5-digit number.
That is, 9,999+1 is 10000.(Ten Thousand) - Adding 1 to the greatest 5-digit number gives the smallest 6-digit number.
That is, 99,999+1 is 100000.(One lakh) - Adding 1 to the greatest 6-digit number gives the smallest 7-digit number.
That is, 9,99,999+1 is 1000000.(Ten Lakhs) - Adding 1 to the greatest 7-digit number gives the smallest 8-digit number.

- The total of 42, 75, 189, 301, and 728 is
- Right triangle PQR is to be constructed in the xy – plane so that the right angle is at P and line PR is parallel to the-axis. The x and y coordinates of P, Q, and R are to be integers that satisfy the inequalities: –4 ≤ x ≤ 5 and 6 ≤ y ≤ 16. How many different triangles could be constructed with these properties?
