I’ve been practicing a bit lately and have been looking in occasionally. If you are merely around 150 ( 1 in 1000 ) then you probably need to work on it. On the plus side, IQ is fairly normally distributed and if you score +175 or so ( 1 in a million) then you can probably figure it out yourself. The gifted are really, really annoying but us “normals” can appear to be pretty smart until someone gifted comes along. Those of us without gifts can become reasonably proficient with sustained practice. … Start young 3 or 4 would be nice and have talent. Play with numbers, sequences, and logarithms Learn some new mathematics play with calculus, linear algebra, stats, and probabilities. You need to become proficient, efficient and confident. Practice - there is no substitution for practice, your brain needs to become efficient in recognizing and calculating. Or possibly faster depending on your strengthsģ40 + 153 = 493 ( 17 doubled and 9 * 17 = 1 3 ) whichĪlthough recognizing that 23^2 = 529 - 36 = 493 could even be faster if you can just trust it.įastest yet is simply committing 29 * 17 = 493 to memory and the leveraging the fact in larger calculationsĪddition and subtraction by Anzan, mental visualization of abacus are far faster than rational thought as well.Ī strong grasp of a major system and a small journey should provide the ability to hold more than 7 sub-totals while simultaneously calculating.īeing able to estimate and cross-check your work trivially logarithms.Īpplications - use it for something other than its own benefit. So that you can look at 29 * 17 and say to yourself 510-20+3=493 without much thought to get to around 1 second. If you are thinking about 67-9 is 67-10 + 1 then it is too slow To be really fast you need facts and you need to be able to compute with patterns or inherently trusted algorithms ( For the mental math, just practice on zetamac and graduate trader. other techniques - Anzan, major system, journey. Mental math test mental math test ask you to finish some mental math test as. algorithms - tricks, the difference of squares, distributivity.facts the more things you know the faster you can pivot.That said you are going to want to build skills with them.
