  • okay i'm gonna go ahead and start uh... today's workshop is called memory tricks and

  • the reason that next week's workshop is called more memory tricks is because

  • i know a lot of tricks

  • and i can't get them all in one workshop so more of the same next week

  • if you find today's workshop helpful which i hope you do

  • and you're able to come back next week that would be great 'cause that way you get sort

  • of the full teaching on this

  • if you're not able to make it next week and this is the only one you come to hopefully

  • you'll still get something good

  • my first thing that i'm gonna do with you today

  • is to show you hopefully the power of that word

  • the word tricks

  • i gave a workshop last week called how to remember for tests so that was the first memory

  • workshop but for this one

  • what i want you to try to uh... understand and sort of value

  • is the fact that if you learn tricks or shortcut ways

  • to do things

  • it makes it so much easier to memorize lots of things for school

  • and it makes your memory look even better than it is now

  • and i'm hoping it's pretty good to very good but it makes it look even better and so most

  • of you have probably seen magic tricks performed before uh... either in person or on t_v_

  • and if somebody is a good magician

  • and they do uh... trick and you watch carefully and try to figure out how they

  • move the elephant from there to there or cut someone in half and put them back together

  • if they're good

  • you can't figure out how they did it and your mouth

  • drops open wow

  • but if you find out how they do the trick

  • and you realize ah it's just a cute little trick and then you see

  • the magic trick again

  • it's not so special anymore because the magic is gone

  • well i want to show you two things to start with and i'm actually gonna do this

  • next week too this is like your mental warm up before i get to the

  • main teaching

  • uh... i don't know what your attitude is toward

  • math

  • some people love math

  • some people okay

  • and some people hate math with a passion

  • i ran into a former student today and i said how are your classes going this semester she

  • said fine except math

  • and that's how she says math

  • and so if that's you

  • you're gonna learn something here if you like math great a few of you might have seen this

  • before but again it's not to teach you math as much as it is to show you the power of

  • tricks ok so i'm just going take a few minutes with this and then we'll move into the main a section

  • of the

  • workshop okay

  • if i ask you to do this problem which i don't want you to do actually but if i asked

  • you to do this on paper

  • this is thirty five times what

  • thirty-five

  • now even if math is your weakest subject if you wrote down that problem and you did the

  • problem i think everyone here could come up with the right answer you know it's not that

  • difficult

  • but if i told you

  • that you could actually

  • do this kind of problem

  • in two or three seconds

  • in your head

  • most people even if they're not great at math would think

  • uh... boy

  • you don't know my mind i can't do something like that but if you know the trick it's easy ok

  • so here's how it works

  • when you have a two-digit number that ends in five and you want to square it or multiply it by itself

  • all you have to do is one simple thing and that is

  • look at the first number which in this case is three

  • multiply it by one more than that so

  • this is tough math what's one more than three

  • what's three times four

  • twelve that's pretty easy right well twelve and then

  • you do one more thing

  • and that is stick the number twenty five on the end

  • and then you're done that's it

  • one thousand two hundred and twenty-five is the answer

  • people when i show them that they say

  • wait a minute but how did you

  • and you know what i always say who cares

  • as long as it works you don't even have to know why it works it just does so if i give you

  • sixty-five squared

  • you're supposed to be able to know how to do that quickly unless i've lost you over here

  • which is ok

  • it's six times seven which is

  • forty-two and then

  • twenty five

  • okay and that's it

  • when

  • i show this to people also and they learn how to do it and they think wow that's fast you

  • know that's good one thing that they ask is

  • does this work with all numbers

  • and my answer to that is no

  • if it worked with all numbers we would all be math majors right 'cause this is really

  • easy but there are a lot of other math tricks a lot of them and i'm gonna show you one more

  • in a minute but here's what i wanted to to tell you

  • um... i have actually had

  • students try this before and whether you do this or not is up to you but it's kind

  • of

  • fun to experiment with it or try it and that's this

  • um... once somebody learns how to do this even if they don't understand why it works but

  • they just know the two little steps

  • very often i've had students go up later today to someone they know

  • family member

  • friend

  • classmates somebody and they walk up and they hand them a piece of paper and a pen or pencil

  • and they say this

  • and if you do this this is what i want you to say

  • i want you to choose a number

  • that is two digits and ends in five

  • and you square it on paper

  • and i'll do it

  • in my head

  • and we'll see who finishes faster

  • so in other words trying to show off your great math ability okay

  • so the person looks at you

  • and i've had people even do this with family members who knew they were bad at math

  • and this really blows the mind of somebody like that so they say okay two-digit number

  • that ends in five

  • they say yeah okay how about twenty five

  • and so they write the problem the way that it normally is written

  • by the time they finish writing the problem you should already know the answer

  • and they haven't even started figuring it out yet

  • what's the answer to that

  • yeah six twenty five 'cause it's two times three is six twenty five

  • so what you do

  • to impress them

  • is before they've even done anything you tell them the answer

  • but you don't say it like this

  • six twenty five

  • you have to have an attitude about it you see it this way

  • six twenty five

  • like come on give me something tough and they're going to look at you and they're going to

  • think

  • get out of here

  • and then they're gonna start

  • going through and doing the problem the normal way and then at the end they get the

  • same answer that you got

  • and they're going to look at you

  • i guarantee you and they're going to say

  • how'd you do that so fast

  • if they ask you

  • this is the only time i'm ever going to say this ever

  • lie

  • don't tell 'em

  • say this this is my favorite things say this i can't tell you how i do the problem like that so

  • quickly but

  • i've been lying in bed till two o'clock in the morning everynight learning to move the

  • numbers in my mind

  • and they'll look at you and go wow...

  • and they'll say wish i could be as good as you are

  • and then here's the hardest part you have a straight face no smiling or what ever you

  • look at 'em and say well

  • you keep working on it and maybe one day you'll be as brilliant as i am and that's hard for

  • you to say because you know that it's just a simple trick

  • but what they think when you're able to come up with something that fast is that you're

  • basically doing this

  • and you're doing all these

  • things and you're not doing any of that

  • well it's kinda nice

  • to be able to do something like this

  • and impress somebody ok now

  • if they ask you a day or two or three later if you see him again and they say

  • can't you tell me how you do those problems so fast i'm still thinking about that

  • go ahead and say all right i'll tell

  • and then show them this

  • and watch their great admiration of you just drop and they'll just look at you like they thought you

  • were special because it's not special but if you don't know how to do it

  • it looks fantastic okay so that's the idea with tricks and then i'm gonna to show you one other
