During another game, Patrick scored points by making 2-point shots and by making 3-point shots. The two expressions below represent the number of points he scored from making 2-point shots and the number of points he scored from making 3-point shots.
2-point shots: 2 \times (4+6)
3-point shots: 3 \times (2+3)
Patrick claims he scored twice as many points from making 2-point shots as from making 3-point shots since 4+6 is twice as large as 2+3.
Explain why Patrick's claim is not correct even though 4+6 is twice as large as 2+3.
