What is 2 X 2 + 2 X 2 + 2 - 2 X 2 ?

Be careful with a problem like this. People might say there are several answers depending on what operation is performed in what order. That's why there are the order of operations to follow.

By following the order of operations, the answer is 6. Follow the order of operations and perform from left to right. Multiplication comes before addition and addition comes before subtraction.

4 + 4 + 2 - 4
10 - 4
6
