To find the sum of the numbers 1, 9, 2, 3, 5, and 18, we need to add them together step by step.
First, we can group them for easier addition:
- 1 + 9 = 10
- 2 + 3 = 5
- 5 + 18 = 23
Now, we can add these intermediate results:
10 (from 1 + 9) + 5 (from 2 + 3) + 23 (from 5 + 18)
This simplifies to:
10 + 5 = 15
Now, add 15 + 23:
15 + 23 = 38
So, the sum of the numbers 1, 9, 2, 3, 5, and 18 is 38.
