In this video I show how to memorize squares of numbers up to 25 which will let you recall them in 2 seconds or less.
From my experience memorizing by association is much more efficient that memorizing by repetition.
I also make association not with random objects, but with number being squared or neighbor squares, which helps you recall the association easily.
First 25 squares are fundamental to calculating squares of bigger numbers - up to 100 an beyond - because of recurring pattern in the results. That will be covered in later episodes.
Calculating squares quickly also helps you use Method of Squares for multiplying two numbers, covered in my other videos.
On my channel you will find other videos with fast calculation methods, but also with logic puzzles and problem solving techniques.
