This is simple and tasty. Pour canned pineapple with liquid in bowel over the top of shredded carrots. Add raisins. Scoop mayonnaise on top of these ingredients. Then add sugar on top of mayonnaise. I find adding in this order provides the liquid mix necessary for a great salad. Now, take a wooden spoon or other large spoon and simply stir the mixture until well mixed. Put salad in refrigerator at least 2 hours for best results.
