The video tutorial covers various math problems from the 2018 Grade 4 New York State Test. It begins with identifying perpendicular lines in diagrams, followed by solving a division problem involving flowers and vases. The tutorial then calculates Samantha's total walking distance using fractions, and uses division to determine how much Monica recycled compared to Cindy. It also includes a problem about the fraction of rabbits at a pet show, calculates angles in a right triangle, and ends with a multiplication problem to find the total number of erasers bought by a teacher.
