Blanch has 15 slices of pizza in the fridge. During breakfast, she eats 4 slices. At lunch, Blanch eats 2 slices, then takes two slices as a snack. Finally, she consumes 5 slices for dinner. How many slices of pizza are left?
During breakfast, Blanch has 15 - 4 = <<15-4=11>>11 slices left.
At lunch, she still has 11 - 2 = <<11-2=9>>9 slices left.
After the snack, there are still 9 - 2 = <<9-2=7>>7 slices left.
Finally after dinner, Blanch has 7 - 5 = <<7-5=2>>2 slices left.
