    I’m compelled to tell viewers how my son learned the tables after coming home from school. I wrote tables of 1-10.
    I told him not to memorize because that would have burdened him but only read it daily.
    After a number of days the tables embedded in his mind. Upon asking any 2 digits he would give the correct answer.
    I then went from 11 to 20.
    At 44 now, he can answer multiplication of any numbers on that table.
    The viewers, their kids or grandchildren may benefit and wouldn’t burden or stress themselves. Reading is easier than memorizing. However reading again and again and again automatically gets embedded.

    I found out that doing it the school taught way was faster on paper, but in your head, this was faster. Plus we are all used to the school way, cause we have been practicing math that way. If I practiced these methods, I would certainly be faster than a person with a calculator or using the school-taught way. Thank you for your great advice on math, I will continue to strive for my goals. Just started these methods a couple of days ago and I feel like I'm slowly becoming faster. Thank you.

    I have another way to do a square of two digit numbers that start with 1.
    For example:-
    12×12
    So first we are going, to just multiply 2 with 12 which is 24, then we are going to plus 24
    12×
    Which is 144. This doesn't seems the simplest but it is easier for me.

    There is another easy method for squaring two digit no..... For example let's take 23 so here we need to do square of 2 which will be 4 and then we need to multiply 2 with both the no. So 2×2×3 and then again square of 3 which is 9.....so overall it will be 4 12 9...where the 1 will be added to 4 and the answer will be 529....and I think it's much easier and quicker... thankyou ❤️
