# Math Tricks Multiplication Tricks Easy Math Math Made Easy

As a computer science major, I have to say that I love math. One big reason people don’t care much for math is because they are afraid of it. Like anything else in life if you fear it, it will be hard to overcome. Perhaps, if you think of math like another language it may not be as hard to handle, after all mathematics is just another type of language, instead of letters to form words and sentences, numbers form problems, answers, and solution. We use math every day in our life, in some form or another.

One way to help people over come there fear of math is to try and make it fun. Yes, you heard me math can be a lot of fun. Most of the fear people have can be lessened if they learn to have fun with math. You know just about every card trick every invented was done so by mathematics. You can link almost every aspect of life to some form of math or another. So if you can’t avoid it have some fun with it.

I think what most people fear about math are the multiplication aspects. Division, subtraction, and addition are not as feared. Everyone should know how to multiply by zero, its simple anything multiplied by 0 =0 that’s was easy. To multiply by one is very simple as well; anything multiplied by one is the same number. Example 2 x 1=2 or 50 x 1 = 50 no major deal there either. Now we move to two again not a hard number to do. All you do is double the number, so 2 x 10 = 20, or 55 x 2 = 110 this is the child’s play of the multiplication table.

Now it starts to get a little tougher here when you start with the 3’s, but just think of it like this. You want to multiply 5 x 3 well you know how to do 5 x 2 = 10 well just add another 5 to it and you get 15. Therefore, you double your number and ad the number to that. Let’s say you want to do a number like 3 x 1460, well if you double that it becomes 2920 right now just add 1460 to that and you have 4380, so 3 x 1460 = 4380 not so bad huh.

Okay let’s move on to the 4’s again not a real hard number to work with. You can multiply by 2 you can do it by 4 as well you just double your number twice, so 4 x 4 would be 4+4=8 and 8+8=16 let’s take a bigger number like 1322 you add 1322 + 1322 = 2644 then you add 2644 + 2644 and you get 5288, so 1322 x 4 = 5288 not so bad right.

Now we start to get into the tougher numbers like 5, but it really isn’t that hard watch. First, the easiest way to multiply by 5 is actually multiply by 10 and then divide by two, for example: 5 x5= 5 x 10/2 or 5 x 10 = 50 and 50/2 = 25, so 5×5 = 25. Let’s try a harder number now 5 x 69 which equals 10 x 69/2 or 690/2 =345, so 5 x 69 = 345. Not too bad when you do this way is it.

Now let us move to the 6’s this is another one that can be a challenge to most people, but like the rest there is an easy way to do it. Whatever number you are multiplying to 6 you would divide by two then multiply by 10 then add the original number on to that. I know sounds tough, but it’s not, here is a few examples. Take and easy one like 6 x 10 we know it equals 60 but look at it like this take 10/2 = 5 multiply it by 10 and add back the original number 10 5 x 10 is 50 + 10 is 60. Let’s try a harder one now. 6 x 15=90 15/2 = 7.5 x 10= 75 + 15 = 90 this is stuff you can do in your head and really impress your friends.

I am sorry but I don’t really know a quick way to do the number 7. I always tried to memorize my 7 tables that was the only way I could get it done. I guess we can jump to 8 then. Like 2 or 4, 8 is just a number you want to work with doubling in a way. Let me show you let’s do 8 x 10 okay you take 10 x 2 = 20 then 20 x 2 = 40 then 40 x 2 = 80 simple concept there. Let’s try one a little harder like 8 x 24 = 2 x 24 = 48 2 x 48 =96 and 2 x 96 =192 and there, you have your answer.

Now we go into the ever so dreaded number 9 for some people this is the worst of them all, but there is a very easy way to do the 9’s as well. You work with the 9’s as if they are 10’s instead. Say you want to multiply 9 x 8 =72 look at it like this multiply 10 x 8 instead you get 80 now subtract the original number 8 leaving you with 72. Let’s try a harder one like 9 x 18 = switch to 10 x 18 = 180 and subtract 18 leaving you with 162 the answer not so bad now right. I don’t think we need to worry so much about the ten’s they are just as easy as the 1’s.
