I am two digit number first from right
To determine the value of a two-digit number where the digit on the right is known, you can follow these steps:
1. Assign a variable for the unknown digit on the left. Let's use 'x' as the variable.
2. Write the number in the form of 10x + y, where x represents the unknown digit on the left, and y represents the known digit on the right.
3. Since the number is two-digit, both x and y should be integers from 0 to 9.
4. Consider the possible values of y and solve for x:
- If y is 0, then the value of x can be any digit from 1 to 9. For example, if y = 0, the numbers can be 10, 20, 30, and so on.
- If y is not 0 (1 to 9), then the value of x will always be 0, as there is no other digit on the left. For example, if y = 1, the numbers can be 01 (which is equivalent to just 1), 11, 21, 31, and so on.
Therefore, if you are looking for a two-digit number where the first digit from the right is known, you can either have any digit from 0 to 9 on the left, or the digit 0 on the left if the right digit is not 0.
