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

### 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:
 รวมกันทั้งหมด 26 + 34 + 22 = <<26+34+22=82>>82 ซม. ตกในสามวัน
ถ้า 140 ซม. เป็นปริมาณเฉลี่ยในสามวันแรก แล้ว 140 - 82 = <<140-82=58>>58 ซม. น้อยกว่าปริมาณเฉลี่ย.
