Use your fingers.
Hold down the first finger on your left hand, nine fingers remain up. The answer is 9
For two hold down the second finger on your left hand. On the left is one finger standing, and on the right are 8 fingers standing. The answer is 18
This pattern works for everything up to ten. Then you remember 9 x 11 is 99. And 9 x 12 is 108
a + b = 60 (1)
b < a with 6 ⇒ b = a - 6 (2)
(1), (2) ⇒ a + a - 6 = 60 ⇒ a + a = 60 + 6 ⇒ 2a = 66 ⇒ a + 66:2 ⇒
⇒ a = 33 (3)
(2), (3) ⇒ b = 33 - 6 ⇒ b = 27
So, the numbers are : a = 33, b = 27
