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

### Instruction:
Thomas is keeping track of the rainfall in May for his science project. On the first day, 26 cm of rain fell. On the second day, 34 cm fell. On the third day, 12 cm less than the second day fell. The average rainfall for the first three days of May is usually 140 cm across all three days, in a normal year. How much less is it raining this year than average?

### Response:
 Jumla ya mvua iliyonyesha ni cm 26 + cm 34 + cm 22 = <<26+34+22=82>>82 kwa siku tatu.
Kama cm 140 ni wastani kwa siku tatu za kwanza, basi cm 140 - cm 82 = <<140-82=58>>58 kidogo kuliko mvua ya kawaida.
