Mark Symmonds – Chatsworth International School, Singapore Just like when we count, start from the left. 1, 2, 3, 4, 5, 6… As we are looking for 3 multiplied by 9 we count across to our 3rd finger and move it down. 2 1 3 3x9= Marker Finger 1x9=9 2 x 9 = 18 3 x 9 = 27 4 x 9 = 36 5 x 9 = 45 7x9= Marker Finger 1x9=9 2 x 9 = 18 3 x 9 = 27 4 x 9 = 36 5 x 9 = 45 6 x 9 = 54 7 x 9 = 63 8 x 9 = 72 9 x 9 = 81 10 x 9 = 90 9x9= 1x9=9 2 x 9 = 18 3 x 9 = 27 4 x 9 = 36 5 x 9 = 45 6 x 9 = 54 7 x 9 = 63 8 x 9 = 72 9 x 9 = 81 10 x 9 = 90 Marker Finger 1x9=9 2 x 9 = 18 3 x 9 = 27 4 x 9 = 36 5 x 9 = 45 6 x 9 = 54 7 x 9 = 63 8 x 9 = 72 9 x 9 = 81 10 x 9 = 90 11 x 9 = 99 12 x 9 = 108 The tens digit is always one less than the number you are dividing! Remember there are no tens digit in 1 x 9 as the answer is 0 tens and 9 units! This pattern only works up until 10 x 9 9 added to nothing equals 9 If you add both the digits of the answer together they will always equal 9. So if we take 7 x 9… The tens column in the answer is always one less than the one you are multiplying. We know the answer will start with? 6 And the two digits added together make nine so 6 and what make 9? 3 So we know that the answer is 63. so… 1980 so… so… 5445 so… so… 12177 so…
