Mary is baking a cake. The recipe calls for 11 cups of sugar and some more cups of flour. She already put in 3 cups of flour. If she still needs to add 6 more cups of flour how many cups of flour did the recipe require?
First, we know that Mary has already put in 3 cups of flour. 

Next, we know that the recipe calls for 11 cups of sugar and some more cups of flour. 

From this, we can infer that the recipe requires a total of 11 + some cups of flour. 

Lastly, we know that Mary still needs to add 6 more cups of flour. 

From this, we can infer that the recipe requires a total of 3 + 6 + some cups of flour. 

Therefore, the recipe requires a total of 3 + 6 + some = 9 + some cups of flour.
