The video introduces investigative math, focusing on tricks for calculating the sum of squares. The first trick involves recognizing when a number squared is added to three times that number squared, simplifying the calculation by multiplying the smaller number squared by 10. The second trick applies when a number squared is added to two times that number squared, where the smaller number squared is divided by 2 and then multiplied by 10. The video concludes with a problem set for practice and encourages viewer interaction.
