Subtraction of 3-Digit Numbers Without Regrouping

The video tutorial at Uncle Joe's Farm teaches subtraction of three-digit numbers without regrouping. It begins with an introduction to the concept using green and red chilies as examples. The tutorial demonstrates subtraction using a visual method with dots and a direct method using a place value chart. Two examples are provided: one with chilies and another with wooden boxes and potatoes. The video concludes with a reflection on the day's activities at the farm.
