Interesting..

Yesterday while studying math.. i rember this certain thing that happend in the past while i was in school in uk...there is a way to know the 9 times table by using ur hands...i wish i cud show u some who i figured it out...anyways since the exam we cant have calculaters..then i told my mum and she showed me something more amazing:
Check it out:


Nine Times Table


9 x 1 = 9 = 9 + 0 = 9

9 x 2 = 18 = 1 + 8 = 9


9 x 3 = 27 = 2 + 7 = 9

9 x 4 = 36 = 3 + 6 = 9

9 x 5 = 45 = 4 + 5 = 9

9 x 6 = 54 = 5 + 4 = 9

9 x 7 = 63 = 6 + 3 = 9

9 x 8 = 72 = 7 + 2 = 9

9 x 9 = 81 = 8 + 1 = 9

9 x 10 = 90 = 9 + 0 = 9


---LOOK ...the number go from 1 -8 then go up from 8 -1 ---

isnt that amazing!! weird!! sij my mum said its 3ajeeeb now this is my fave times table!...see how the number r back wards like 18 then its 81...like a mirror!:)
enjoy:) see math can be fun!

Dear D,

again... I am back on your blog because of amy lee.. Kepp that avatar.

Now, to your post. I've been using this trick since I was 7

That's the ONLY way I know of learning the 9 times table.

How about a trick for the 6 times table... that is hard to learn.

truly,
Misguided

P.S. I will gladly lend you a calculator if you need one :)

Notice that all the answers add up to nine as well.

27 -> 2 + 7 = 9
36 -> 3 + 6 = 9

and so on :)

There is another way to do it too

Hold out 10 fingers palms facing you. Put down your 1st finger from left to right (left thumb). You have 9 fingers, that is 9x1.

Put down your next finger over and raise your thumb. The thumb that is seperated from the rest is the 10's place and the rest is the ones. So you have 18 (9x2)

Lift your pointer now and lower the middle finger next to it. Now you have 2 fingers up, a space and 7 fingers. 2 finger are the tens and 7 are the ones, 27 (9x3).

Count over from left to right and lower the 6th finger (6x9) (which happens to be the pinky on your right hand) and you get 5 up, space, 4 up, 54!
