Re: Help me :) i need help :)
Hi joe, which ones were you having trouble with?
If you just want practise, you could try here: http://www.mathsisfun.com/timestable.html
Or you could use this colourful chart.
If you're having trouble remembering them, tell us the ones which you need help with and we can give you some tips.
Re: Help me :) i need help :)

There are many systems for remembering numbers. I personally use the popular phonetic system which works great for me for everything from remembering phone numbers to things such as the first five hundred digits of pi.
A pretty good explanation of this system can be found here:
http://www.mindtools.com/majorsys.html
There are memory "tricks" for remembering anything, with many originating with problems first encountered by ancient Greeks. Some authors that I would personally recommend in this area are Tony Buzan, Sanderson, and Lorayne. Not only are these techniques very useful, but they are also quite fun to put into practice.

As a side note, does anyone know why such methods are not being universally used in the world's educational systems? They work so naturally and efficiently that I think the educational institutions are "stupid" not to teach them. Just my opinion.

Really try to apply the ideas that you find there before dismissing them. Once you get comfortable with the system, it could literally transform your life.
Have fun!

i just got home and now checking it out and the computer is working

If your computer wasn't working, I would seriously be freaking out right now.

LOL...
And Irspow, that website was very interesting...how long did it take you to become comfortable with that system?
We may not teach it in schools because it is not really a universal way that people learn things (that's not to say that any one universal way even exists)...For example, it is easier for me to just memorize a phone number than it would be for me to memorize a sequence of words that represent the number in my mind...

Re: Help me :) i need help :)
Oh, and I forgot...the point of my post... I remember learning threes and twelves from Schoolhouse Rock...(this may be too old for most of you to remember, but they sell cd's at record stores) So, one option is learning in singsong! It is a really easy way for your brain to remember...

Yes, that it how I learnt most of them! I had a times tables CD by Don Spencer.

Re: Help me :) i need help :)
First memorize these ones: six times six is thirtysix, seven times seven is fortynine, eight times eight is sixtyfour, and nine times nine is eightyone. Next memorize these ones because the answers are one below the answers of the other ones I just did. five times seven is thirtyfive, six times eight is fortyeight, seven times nine is sixtythree, eight times ten is eighty. Next memorize these ones because they are three less than the ones I just did. four times eight is thirtytwo, five times nine is fortyfive, six times ten is sixty, seven times eleven is seventyseven. Also if you know that 5 times 5 is 25, then you automatically know 3 times 7 is 21 because it is four less. This is the difference of two squares. (5 times 5) minus (2 times 2). You see 3 and 7 are two away from 5, so 2 times 2 less than 25. So that's why you should know 4 x 4 = 16 because then you automatically know that 3 x 5 is one less. And 4 x 6 is one less than 5 x 5. And 8 x 10 is one less than 9 x 9. So learn the same numbers multiplied by self first. So 2 x 9 is 11/2 times 11/2 subtract (11/2  2)^2.
The ^ sign means to multiply by same number. So for 2 x 9, it is too hard to use this method because 2 and 9 are not both even numbers. Also 2 and 9 are not both odd numbers. 2 and 9 are one of each, so memorize those ones. 3 x 6 is double 3 x 3 or 9 x 2 is 18. Good Luck!

Make a "singsong" of the first 500 digits of pi! I guess that it could be done, but I memorized the 500 digits in about an hour or so. The system works great because it does use the natural way that your brain works.
darthradius, I learned and was comfortable using the system in about an hour. I could use it without any extraneous thought for any number within about a week. I was actually introduced to the system in one of Harry Lorayne's books. It, "Super Power Memory", sparked a growing interest that has continued to this day in the area of memory techniques. I have since then, read about 30 books on memory techniques, and at this point I have a firm grasp on just what causes most people to remember things, or forget them for that matter.
Oh, and you don't really remember words, I don't and I feel that I truly understand most of the techniques out there. They are really based on the images and not the words associated with them. As the experts agree on this point, it is the conceptual images in our minds that we use to define words to ourselves, not the other way around. If I had to memorize a long list of words, it would be nearly impossible, but stringing together a very long sequence of images is easy to recall.
The basic link and peg systems out there are only the beginning for someone who truly wants to tweak their mind. After you learn a handful of the common systems out there, you find yourself creating new systems unique to your special gifts. After you master your own systems than you can move even farther toward extreme learning. This area is best covered by individuals like Tony Buzan who pioneered "mindmapping" which takes the near infinite power of the basic systems to ridiculously higher levels.
I believe that anyone who puts forth an even slight effort into learning any of the systems out there will amaze themselves with the nearly infinite memory that they already have but don't know how to use.
I guess it's a little obvious that I am a passionate supporter of memory techniques, because I know how amazing the results can be. As for these systems not being universal being used as an excuse for their noninclusion within the educational establishment. What exactly are you told is the best way to study and retain information in school? I have seen how a lot of people study, and to be honest, it is truly pathetic. Putting forth a thousand times the effort necessary and retaining only a small fraction of what they "learned". It's sad. I will state again(?) for the record, a subject devoted to mind enhancing techniques would be far more beneficial to students than many of the other areas covered.
I think that if we taught kids this in kindergarten, rather than having them eat glue and paint, a much higher percentage of the population would grow up to be what we like to call a "genius".
Re: Help me :) i need help :)
After that you can figure out the rest
with the LessThanATwin way.
Say you need to know 3 times 9. It is 27, but you don't know that, so you check that 3 and 9 are both odd, and they are, so find the number that is right between 3 and 9. It is 6. Now 3 and 9 are three away from the middle number 6. So we have to subtract three three times from the middle number times the middle number. So 6 times 6 is 36 because you have to memorize the twins. And 3 times 9 is this 36 minus 3 minus 3 minus 3. I subtracted 3 three times because 3 and 9 are three away from the middle.
Here is an easier one. Say you want to know what 4 times 8 is. Both numbers are even, so we can figure it out. The middle number is 6 again. And 4 and 8 are two away from 6. So now we subtract 2 from 6 x 6 two times. So 36 minus 2 minus 2 is 32, and that is 4 times 8. 4 x 8 = 32. Here is the easiest one. Say you want to know 7 x 9. They are both odd and the middle number is 8. 7 and 9 are one away from 8, so subtract one one time from 8 times 8. So 8 x 8 you have to memorize because it is a twin. So 8 x 8 minus one is 63. So 7 x 9 is 63.

Also, you don't need to know 3 x 6 if you know 4 x 5 because 3 x 6 = (3+k)(3+k+1)  k(k+1), where k=floor((63)/2).
So now you only have to memorize the twins, really called squares, and the numbers that are right beside each other, also called consecutive numbers.
