The
numbers 17, 35, 62, 73, 86, 97 are used
in the video.
Example : 17 x 11 Leave a space between the 2 digits : (1 ___ 7) Add 1 + 7 (1+7=8) Insert the result (8) into the empty space. Therefore 17 x 11 = 187 When the result of the addition is more than 9, insert the "unit" digit into the empty space and carry the "tens" digit from the addition. Example : 73 x 11 7 ___ 3 7+3 = 10 Place the 0 into the empty space. Add the 1 and 7 (1+7=8) Therefore 73 x 11 = 803 Watch the video |
