A Possible Trick for Calculating Percentages
http://www.curiousmath.com/articles/Possible-Trick-for-Calculating-Percentages.html
A Possible Trick for Calculating Percentages. Sometimes a difficult percentage calculation can be made easy simply by swapping the two terms. For example: In your head, you may find it difficult to compute 18% of 25. Instead, try solving for 25% of 18. 25% is just half of half of any number. Half of 18 is 9, and half of 9 is 4.5. Since 25% of 18 is 4.5, it is also true that 18% of 25 is 4.5. Submitted by former curiousmath.com member "deud". Back to the home page.
Square Roots by Hand
http://www.curiousmath.com/articles/Square-Roots-by-Hand.html
Square Roots by Hand. If you're good with long division, here's a quick way to find pretty accurate square roots without the aid of a calculator. Let's try 24.6. Make a guess. It can be a very bad guess. It doesn't matter. You can even guess 1. Let's try 5 since (5 {2} ) is 25, which is pretty close to 24.6. Divide 24.6 by 5. ( frac{24.6}{5} = 4.92 ). Now, comes the trick: Pick a new guess between 5 and 4.92 and divide it into 24.6 again. Back to the home page.
Computing the Sum of All Numbers from F to L
http://www.curiousmath.com/articles/Computing-the-Sum-of-All-Numbers-from-F-to-L.html
Computing the Sum of All Numbers from F to L. If you want to add all the numbers from F (First) to L (Last), here is an easy way to do it, and many times can be performed in your head. Sum {F} {L} = (L {2} - F {2} F L)/2 ]. Where F is the first number in the number line and L is the Last. To add all the numbers from 1 to 10, plug in 1 for F and 10 for L. 10 {2} - 1 {2} 10 1)/2 = ). 100 - 1 11)/2 = ). 110/2 = 55 ). The result is the same as adding all the numbers from 1 to 10 like this:.
Curious Numbers
http://www.curiousmath.com/articles/Curious-Numbers.html
When Srinivasa Ramanujan, the great Indian mathematician, was ill with tuberculosis in a London hospital, his colleague G. H. Hardy went to visit him. Hardy, trying to initiate conversation, said to Ramanujan, "I came here in taxi-cab number 1729. That number seems dull to me which I hope isn't a bad omen.". Simon Peter went up, and drew the net to land full of great fishes, an hundred and fifty and three. And for all there were so many, yet was not the net broken.". Four interesting things about 153:.
