    How to do 1565 x 1197 in 10 seconds without a calculator and paper?

    it's called vedic math. if you google it, you'll find a ton of sites with math tricks here and there. but usually, they don't involve numbers that big. for example: when multiplying 2, 2-digit numbers with the same tens digits and two ones digits that add up to 10, (ex. 23 x 27 ) the vedic stuff...

    How Much Does the Envelope Cost in the Riddle?

    it's 30. there are 6 guys, and they each shake hands with 5 other people. so for the first guy; he shakes hands with 5 people, meaning there are 5 handshakes for that one guy. for the 2nd guy, there are another 5, for the 3rd there are another 5, and so on. so you do 6 x 5, which gives...

    What Is the Next Number in This Mathematical Sequence?

    yeah i got 63 too, but in a different way i think. basically, the differences between them respectively, are 1, 7, 5, 11, 9, and 15. divide it like this: 1, 7, 5, and 11, 9, 15 then take the sum of the last two digits in the first set, and subtract the first. so in this case, 7 + 5...

    Next Number in the Sequence: What is the next number in this sequence?

    i got 40. my work looks like this; good luck figuring it out, and let me know what you think. it's probably wrong anyways. 4, 8, 9, 10, 12, 16, 18, 20, 24, 25, 27, 28, ... 40 4 1 1 2 / 4 2 2 4 / 1 2 1 12/ 8 12...

    Is this a suitable explanation of relativity?

    I'm not 100% sure to be honest, but i do think that the velocity, not only the size, has an effect on the duration of whatever the object is doing, such as moving across your line of vision or something. For example, if you're running at the speed of light, meaning your V = C, then gamma =...
