Answer 2

Let's break down the expression step by step:

1. 2 • 2 - 2 : 2 + 2

   First, perform multiplication and division from left to right: 2 • 2 = 4 2 : 2 = 1

   Now, substitute the results back into the expression: 4 - 1 + 2

   Then, perform addition and subtraction from left to right: 4 - 1 = 3 3 + 2 = 5

   So, 2 • 2 - 2 : 2 + 2 = 5

2. 3 + 3 : 3 - 3 • 3

   First, perform multiplication and division from left to right: 3 : 3 = 1 3 • 3 = 9

   Now, substitute the results back into the expression: 3 + 1 - 9

   Then, perform addition and subtraction from left to right: 3 + 1 = 4 4 - 9 = -5

   So, 3 + 3 : 3 - 3 • 3 = -5

3. 4 • 4 - 4 : 4 + 4

   First, perform multiplication and division from left to right: 4 • 4 = 16 4 : 4 = 1

   Now, substitute the results back into the expression: 16 - 1 + 4

   Then, perform addition and subtraction from left to right: 16 - 1 = 15 15 + 4 = 19

   So, 4 • 4 - 4 : 4 + 4 = 19

Therefore, the three expressions have different values:

1. 2 • 2 - 2 : 2 + 2 = 5
2. 3 + 3 : 3 - 3 • 3 = -5
3. 4 • 4 - 4 : 4 + 4 = 19
