​Introduction to numbers

• Numbers are arithmetic values.

• Numbers are used to convey the magnitude of everything around us.

​​Comparing numbers

Comparing numbers when the total number of digits is different

• ​

• The number with most number of digits is the largest number by magnitude and the number with least number of digits is the smallest number. Example: Consider numbers: 22, 123, 9, 345, 3005. The largest number is 3005 (4 digits) and the smallest number is 9 (only 1 digit)

Comparing numbers when the total number of digits is same

• The number with highest leftmost digit is the largest number. If this digit also happens to be the same, we look at the next leftmost digit and so on. Example: 340, 347, 560, 280, 265. The largest number is 560(leftmost digit is 5) and the smallest number is 265(on comparing 265 and 280, 6 is less than 8).
