    Oh my gosh, I'm learning way more about math just by looking at your videos than I did in my whole entire school life...from elementary to college. Where were you my friend? And I've only looked at 3 of your videos thus far. I'm actually going to start with your #1 video and work my way to studying from them all. Not sure what number it ends at but I'm going to look at them all. Thank you so much. I really, really appreciate your videos of all the videos I've ever watched. I struggled with math my whole life and know I feel like a pro or will be a pro after viewing all of your videos. I'm 51 years young (52 in June) and I know I will master this now by learning from you. Thank you, thank you thank you.

    7:00 Why don't you add the digits of the twelve and sandwich them between.

      He does in the first video of this playlist. I think he just wanted to add variety.

    Thank you so much sir I am grateful for these videos. The things you taught will definitely help me in high school. I’ll teach it to my little sister as well so that she can surprise her primary school teachers. THANK YOU AGAIN ❤️

    57 x 53 = 3021 . . . the second digits add up to 10.

      This problem wouldn't work in this case since the video specifically applies to numbers ending in 5, not starting in 5. So the 5 would have to be in the ones place to work with this method.

      @@sanjananagarur6653 The key is that the ending digits total 10. They don't have to necessarily have to be 5's. In the example above 5x6=30. 7x3=21. Put them both together and voila! 3021 So it absolutely works. Try it with any two numbers that start with the same digit. I.e. 62x68, 44x46, 91x99.
