Jacob is trying to eat less than 1800 calories a day. If he eats 400 calories for breakfast, 900 calories for lunch, and 1100 calories for dinner, how many more calories did he eat than he planned?

How many calories did Jacob eat? ** First add up the calories from all three meals: 900 + 400 + 1100 = <<900+400+1100=2400>>2400
How many more calories did Jacob eat than he planned? ** Then subtract Jacob's goal from the number of calories he actually ate: 2400 - 1800 = <<2400-1800=600>>600
#### 600
