3-Digit Subtraction Techniques Without Regrouping

The video tutorial by Mr. J covers how to subtract three-digit numbers without regrouping or borrowing. It begins with an introduction to the concept and proceeds with examples using base 10 blocks for visualization. The first example demonstrates subtracting 237 from 113, while the second example covers 464 minus 232. The tutorial then moves on to solve two more problems, 987 minus 471 and 859 minus 508, without using base 10 blocks. The video concludes with a summary of the subtraction process.
