    Design a function for an automated grading system that extracts the leftmost digit from a student's numerical answer to assess their understanding of place value concepts. The function should analyze any valid numerical response, regardless of how many digits it contains, and return only the first digit to help identify if students grasp the concept of most significant digits in mathematical operations.
