Subtraction Concepts and Techniques

This video tutorial teaches double-digit subtraction without regrouping. It begins with an introduction to the concept of subtraction, followed by a detailed example of subtracting 35 from 69 using diagrams. The video then demonstrates the same subtraction without diagrams. A second example of subtracting 25 from 46 is provided, first with diagrams and then without. The tutorial emphasizes understanding subtraction by counting back and using columnar representation.
