Suzie made a mistake in the following problem. The mistake was made in Line ___. Only input the number of the first incorrect line. Line 1 7 (6) : 5 + 42 Line 2 7 (6) : 5 + 16 Line 3 42 : 5 + 16 Line 4 42 : 21 Line 5 2

Line 1

7 (6) : 5 + 42

Line 2

7 (6) : 5 + 16

Line 3

42 : 5 + 16

Line 4

42 : 21

Line 5

2

It seems to me that there are mistakes on every line.

However, I cannot see how

Line 1 7 (6) : 5 + 42 becomes

Line 2 7 (6) : 5 + 16

So the mistake occurs in Line 2
