I am so embarrassed to admit this, but I never really learned math as a kid. When I was young, my family moved around a lot. I mean, a whole lot. Often right in the middle of a school year. So, by the time I got to a new school, they would have already covered what I was learning at my last school and been onto the next topic. Or, the polar opposite and I would cover what I knew for the third time. Needless to say, my education was not the most stellar. As such, I never really learned the fundamentals of mathematics. I'm talking really basic stuff. Simple terminology, multiplication tables, and never learned ANY division, etc., etc. Despite this, I never had too much of a problem with testing in high school, always getting fairly high marks in the subject... Skip ahead to now... In the past year, I have been watching a channel on youtube called 'Numberphiles'. And despite many of the things they cover being well beyond me, I am enchanted with the... magic, for lack of a better word, they perform with numbers. I want to do this. I will learn this, by hook or crook or giant mallet to my head. Right now I am reintroducing myself to multiplication tables, as I need them for division and fractions. But, due to my awesome education and some memory problems, I am having some trouble. EX: Off the top of my head, I don't know what 12 x11 is. But I know what 12 x 10 is, add twelve and we get 132... the thing is when I get to numbers further from ten, say 8 (I hate this number) and 7 (I only like this number because of 3)..... It's gonna take be a few moments to think out. 5X7=35+3(7)...56... that takes too long. Upwards of 30 seconds when others can do it in two or three (if that). Now, I could just memorize them, but, after searching around online, I have seen an opinion cropping up that memorization of the tables is a hindrance in the long run, often coupled with the statement 'Would you rather memorize or learn to understand.' or some variation... but each time I see this, this 'method to understand' is never outlined... So... I'm really looking for methods and resources to aid me in this pursuit and relearning the basics so I can get on to the really cool stuff. Right now, I am visiting a site called “MyOpenMath” which has basic courses covering everything from the simple stuff to calculus. But, before I can tackle the big stuff, I need to understand the basics... At any rate, any help, tricks, or tips you could provide would be awesome. Thanks.

(y times) will give you the understanding of what multiplication is, however in order to speed things up as you progress up the levels, you will need to learn the multiplication tables facts off by heart as soon as you can, up to 10 is ok or up to 12 is preferred as these relate to decimal and imperial number systems. This will make for an easier time later in maths and in many other aspects of life in general. You may want to try out this website for learning your tables and testing them against a clock www.12xtables.co.uk as well as many other maths skills. Good luck and keep practicing

For example: Calculating 7x8: 1. 7 x 2 = 14 2. 14 x 2 = 28 3. 28 x 2 = 56 You could also multiply the number by 4 and later by 2. For example, 9x8: 1. 9 x 4 = 36 2. 36 x 2 = 60+12=72 As said before, you just need to learn the tables up to 10 or 12, the bigger numbers are calculated using properties. That trick above always works well for me, try it.
