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

### Instruction:
 Squirrel wa kiume anakusanya karanga 6 na kuzipeleka kwenye tundu lake kwenye mti, akiziongeza na zile 12 zilizokuwepo tayari, na kuzidondosha 1 njiani. Squirrel wa kike analetea karanga 5 zaidi kwenye tundu lao na kula 2. Karanga ngapi zimebaki?


### Response:
 Kuna 12 + 6 = <<12+6=18>>18 karanga.
Squirrel wa kiume anapodondosha 1, sasa wana 18 - 1 = <<18-1=17>>17 karanga.
Squirrel wa kike anaongeza kwenye akiba yao, jumla ni 17 + 5 = <<17+5=22>>22 karanga.
Squirrel wa kike anapokula 2, jumla la mwisho ni 22 - 2 = <<22-2=20>>20 karanga.
