I've used this strategy. Since the thumb on her right hand is the 6th finger from the left, then it mean she is multiplying 9 by 6. With her thumb down, there are 5 fingers on the left, and 4 fingers on the right. Put those together and it is 54. 6 * 9 = 54
She put up 5 fingers on one hand and one finger on the other. On the second hand she counted how many fingers were left. There were 4. On the left hand there were 5 fingers. the five on the left and 4 on the right represent the answer of 54.
