Dear all, Continuing with our blogs on Speed Math. All these techniques are to be practiced daily for at least 15 minutes to get full advantage of them. { Sharing - recently lost someone very dear. Please bear with me. So took a break from blogging. But one has to continue working. As this topic is very useful for students, teachers and parents. It is futuristic as it addresses and refines our fundamentals. Once simple calculations can be handled in the mind, our study in various Science subjects becomes easier.  Planning to cover different topics in competitive Mathematics so as to get the best methods to the reader } Base method multiplication extension 20 as base number +3   +6                  -2   +1             +2   +11 23 x 26                   18 x 21       ...

Dear All, Continuing on our series of different methods of dealing with calculations. Taking help mainly from Vedic Mathematics, then from Abacus and other ancient techniques. They work fine . Subtraction: -   We do from left to right . As we read from left to right, why do we do math from right to left? The endeavor here is to develop from left to right . It builds speed . Eg: - 26-5 = 21, 26-9 =? Generally we borrow from the ten 's digit and then do 16-9=7 for the unit 's place . Then we get answer 17. But now, we do subtraction by 10's compliments . 1 9, 2 8, 3 7, 4 6, 5 5 are compliments as they add up to 10. Now for 26 - 9 = 26 - 09 = 2/ 7 = 17. 2-0=2 , as 9 is greater than 6 . We take the compliment of 9 ie 1 and add it to 6 to get 7 . Now whenever you use compliments slash the digit on the left ie reduce it by 1 . Here 2-1=1 . So the final answer is 17. Eg:-    5643            ...

The value of zero. Dear All, This is an endeavor to further our understanding of the fundamentals of Mathematics. It is not always the hard-work or the work-hard that receives adulation . Here, we w ill be enumerating a series of methods different from our regular practices to ease up our calculations . Once this area is covered , people can concentrate more on the reasoning and logic in Maths. God has actually provided for us early systems like Vedic Mathematics, Abacus and so on. They are very difficult to be picked up at later stages in our lives . If one is already in college or job , where do we get the time for these extra efforts. But believe me dear readers, Vedic Mathematics is the game changer. One does not need to memorize anymore. One who is really good at math in our schools , colleges and institutions , hardly studies. This is mainly because of the techniques used. On observation people especially those going for competit...
