Nora's mother tells her to go and pick oranges from their farm. She picks 80 oranges from one tree, 60 from another tree, and 120 from the third tree. What's the total number of oranges she picked?
Thoughts? Step-by-step reasoning:
After picking 80 oranges from the first tree and 60 oranges from the second tree, she has 80 + 60 = 140 oranges. When she adds 120 more oranges from the third tree, she has 140 + 120 = 260 oranges.
Thus, the answer is 260.
