### Instruction:
 Blanch ana vipande 15 vya pizza kwenye friji. Wakati wa kifungua kinywa, anakula vipande 4. Wakati wa chakula cha mchana, Blanch anakula vipande 2, kisha anachukua vipande viwili kama kiburudisho. Hatimaye, anatumia vipande 5 kwa chakula cha jioni. Vipande vingapi vya pizza vimesalia?


### Response:
 Wakati wa kifungua kinywa, Blanch anakula vipande 4, ambavyo bado vimesalia 15 - 4 = <<15-4=11>>11 kwenye friji.
Wakati wa chakula cha mchana, anakula vipande 2, ambavyo bado vimesalia 11 - 2 = <<11-2=9>>9 kwenye friji.
Baada ya kiburudisho, bado vimesalia 9 - 2 = <<9-2=7>>7 vipande kwenye friji.
Hatimaye baada ya chakula cha jioni, bado vimesalia 7 - 5 = <<7-5=2>>2 vipande.
