Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Andrew installed hardwood flooring in his house. His bedroom took eight wooden planks, his living room took twenty planks, and his kitchen took eleven planks. The guest bedroom took two fewer planks than Andrew’s bedroom, and each of his two hallways took four planks. He accidentally ruined three planks in each bedroom by dragging furniture over them and had to replace them. He ended up with six leftover planks at the end. How many wooden planks did Andrew buy to start with?

### Response:
 Chumba cha wageni cha Andrew kilichukua mbao 8 - 2 = <<8-2=6>>6.
Njia zake za kati zilichukua mbao 2 * 4 = <<2*4=8>>8.
Katika vyumba viwili, aliharibu mbao 3 kila moja, hivyo vyumba vilichukua mbao ziada 3 * 2 = <<3*2=6>>6.
Jumla ya mbao za chumba cha wageni, njia za kati, na vyumba ni 6 + 8 + 6 = <<6+8+6=20>>20.
Chumba cha Andrew, sebule, na jikoni vilichukua mbao 8 + 20 + 11 = <<8+20+11=39>>39.
Hivyo, alihitaji jumla ya mbao 39 + 20 = <<39+20=59>>59 kwa nyumba yake nzima.
Alibakiwa na mbao 6, hivyo alinunua mbao 59 + 6 = <<6+59=65>>65 kuanza nazo.
