3-Digit Subtraction: Mastering Subtracting Across Zeros

This video tutorial teaches how to subtract three-digit numbers with regrouping, focusing on problems where subtraction across zeros is necessary. The instructor uses an example of subtracting 258 from 700, explaining the regrouping process in detail. The video covers how to borrow from hundreds to tens and tens to ones, ensuring students understand each step. The lesson concludes with encouragement to practice more problems.
