So Bob's 10-grain cereal has, in each 1/4 cup, 28 g carbohydrates and 5 g fiber. The fiber isn't absorbed (it's the good stuff that keeps your gut healthy), so subtract it from the 28 g to get 23 g carbohydrates. There are 0.0 g sugars, so no simple carbohydrates. The 23 g are complex carbohydrates, i.e. starches of one sort or another that are broken down more slowly than simple sugars.

The calorie count is in kcal, which is a measurement of heat generated. The grams of protein, carbs, and fat are units of mass and will not add up to the calories per serving - they're different things.
