Why do you think that carbohydrates are not digested in the stomach? (AS2)

The peristaltic movements push partially digested carbohydrates produced by the action of salivary amylase into stomach through esophagus. The gastric juices rich in hydrochloric acid lowers the pH of stomach to as low as pH-1.0. The acidic pH completely kills/ inhibit the salivary amylase. Hence, there is no digestion of carbohydrates in the stomach.
