Try these calculations: 1 x 9 + 2 = , 12 x 9 + 3 = , 123 x 9 + 4 =, ... continue the pattern and see if you can predict the answers before calculating.
first one is 11, second one is 111, third one is 1111 on the RHS is the pattern. Next number is 1234*9+5 = 11111
What you read below is true and follows a pattern:
7 + 7 = 2 8 + 8 = 4 8 + 5 = 1 6 + 9 = 3 10 + 11 = 9
Can you analyze the pattern and find out the answer for: 4 + 9 = ?
