- Multiples of 11
1 x 1 = 1
11 x 11 = 121
111 x 111 = 12321
1111 x 1111 = 1234321
11111 x 11111 = 123454321
111111 x 111111 = 12345654321
1111111 x 1111111 = 1234567654321
11111111 x 11111111 = 123456787654321
111111111 x 111111111 = 12345678987654321
- Mating with '8'
1 x 8 + 1 = 9
12 x 8 + 2 = 98
123 x 8 + 3 = 987
1234 x 8 + 4 = 9876
12345 x 8 + 5 = 98765
123456 x 8 + 6 = 987654
1234567 x 8 + 7 = 9876543
12345678 x 8 + 8 = 98765432
123456789 x 8 + 9 = 987654321
- Multiplication table 9
9 x 01 = 09
9 x 02 = 18
9 x 03 = 27
9 x 04 = 36
9 x 05 = 45
9 x 06 = 54
9 x 07 = 63
9 x 08 = 72
9 x 09 = 81
9 x 10 = 90
- Multiplication of two digit numbers
Example: 97 x 97
97 x 97 = 9409
97 =
100 – 3
97 – 3 = 94
3 x 3
= 9
9409
- Multiplication with 11
36 x 11 = 396
The blue number (here, 9) which is at the middle emerges by adding up the first and second digits (here, 3 and 6)
