A soccer team scored 2 goals in the first half. If they won the game by a score of 2 goals to 1 goal, how many goals did they score in the second half. Commutative property, Associative property, or Identity prorerty

The form of property that would need to be used in this question would be the identity property of addition. This is because an addition equation is needed to find the solution. The identity property of addition states that if you add 0 to a number, the result will always be the same as before you added 0. Therefore, there must have 0 goals scored in the second half, because they scored 2 goals in the first half, and at the end of the match they had still scored just 2 goals.

The correct answer is:

Identity property

Explanation:

The additive identity is 0. This is the number that you can add to any other number without changing it. (A mathematical identity is based on arriving at the same number you started with.)

In this problem, the team scores 2 goals in the first half, and ends up winning the game 2 goals to 1 goal (their 2 to the other team's 1). This means they did not score in the second half; if they had, their final score would not have been 2.

This means we add 2+0 = 2; this is the additive identity.
