Yes it is correct. 9 can be written as 10 - 1 So 117 + 9 = 117 + 10 - 1 Again (117+ 10) = 127, so (117+ 10) - 1= 127 - 1
The set of counting numbers starting with 1 and continuing 2,3,4.....and so on arecalled Natural Numbers.
The number of whole numbers between any two numbers
= (thedifference between the numbers) -1.
The difference between 9900 - 9876 is 24 and 24 -1 = 23. So, there are 23 whole numbers are there between 9876 and 9900.
The difference between two consecutive numbers is 1 and let's consider this difference to be a one step.
The catis at number 3 and the ratis at number 10. Thedifference between 10 and 3 is 7, therefore the rat is 7 steps away from the cat.
