(she never SAID it was math)
At the 'end' of each example, the values in your variables 'a' and 'b'...
Ex 1: a = 2, b = 2
Ex 2: a = 3, b = 3
Ex 3: a = 2, b = 3
Your examples 2 & 3 use pre and postincrementation, which is common not only in Java but most programming languages.
Example 2 uses a 'preincrement' operator, so 'b' is incremented to 3 before its value is assigned to 'a'.
Example 3 uses 'postincrement', so the original value of 'b' (2) is assigned to 'a' before 'b' is incremented to 3.

if a=b=2 then a=2 and b=2 so ab=2x2= 4
