Divisibility Math Tricks to Learn the Facts
... Take the last digit in a number. Double and subtract the last digit in your number from the rest of the digits. Repeat the process for larger numbers. Example: 357 (Double the 7 to get 14. Subtract 14 from 35 to get 21 which is divisible by 7 and we can now say that 357 is divisible by 7. ...

... While not terribly useful in this case, it can be easier if the exponents are large.] 2. In total, there are 640+231+100+91+1003 = 2065 women. Therefore, our (unreduced) answer is 1003/2065, and the problem is asking us to find the greatest common divisor (gcd) of 1003 and 2065. METHOD I: The prime ...

... So, if you have the exact securities A and B as above, and two thirds of your portfolio consists of A and the rest B, then you will get 15% return with 0% risk. Smashing. These equations will actually produce curves on a graph of return against risk, so investors can choose shares with certain level ...

... • To resolve the problem of synonymous forms, we will establish a rule that the first digit of the significand must be 1. This results in a unique pattern for each floating-point number. – In the IEEE-754 standard, this 1 is implied meaning that a 1 is assumed after the binary point. – By using an i ...
