Why You Should Do Your Math Homework

I was making snickerdoodles today (because my sister kept nagging me to make them) and I had to substitute baking soda and cream of tartar for baking powder. One teaspoon of baking powder replaces 1/3 tsp of baking soda and 2/3 tsp cream of tartar. So if I needed 1 teaspoon of baking soda in the recipe and 2 teaspoons of cream of tartar, how many teaspoons of baking powder do you put in the repice? The correct answer is 3 teaspoons. And that, my friends, is why you should do your math homework. By the way, the cookies were delicious.
