Sam wrote down the counting numbers from 12 to 11 (including) a) How many natural numbers did she write?
b) how many digits?
c) what is the sum of all the digits?

Whereby the counting numbers Sam wrote down are 12 and 11, we have;

a) The number of natural numbers = 2

b) The number of digits = 4

c) The sum of the digits is 5

Step-by-step explanation:

The natural numbers are also known as the counting numbers or the ordering numbers and includes positive whole numbers from 1 and above

b) A digit is a number from 0 to 9, which can be used singly or combined to form a number

There are two digits each in 12 and 11, therefore, there are a total of 4 digits in both numbers

c) The sum of all the digits is given as follows;

The sum of the digits = 1 + 2 + 1 + 1 = 5.
