Methods of Addition and Subtraction

This video tutorial covers math exercises from a grade 6 textbook, focusing on addition and subtraction problems. The instructor demonstrates two methods for solving these problems: using nearest round numbers and the column method. The video also includes exercises where students fill in missing numbers in equations. The tutorial concludes with a summary and a preview of the next video.
