The instructions ask the user to assign variables for the weight and value of digit 5 in the number 645231. Counting from the left starting with 0, digit 5 is equal to 6 and it is in the
hundred thousands place, so its weight is 10^5 or 100,000 and its value is 600,000.

The accepted answer is looking for a weight of 1,000 and the digit 5 for a value of 5,000. That would be correct if the instructions asked for weight and value of digit 3 instead.

I think you got confused with the counting. The counting starts from the right to the left - beginning from 0. So, for the value 645231, the digit 5 will have a weight of 10^3 and value_digit_5 would be weight_digit_5 * 5

I think you mean â€śfrom the right starting with 0â€ť. And if you mean this, itâ€™s still wrong. The instructions arenâ€™t asking for the weight and value of the digits at position 5. Theyâ€™re asking for the weight and values of the digit 5, which is at position 3 starting from 0 and counting from the right.

This is a well designed exercise because it allows you get it right (coincidentally) for digit 2, but it catches you if you confuse the concepts
