Answer:

425 + 165 = 590

Explanations:

To add two numbers using expanded notation, you break each of the numbers into their place value constitutents.

425 = 400 + 20 + 5

165 = 100 + 60 + 5

425 + 165 = (400 + 20 + 5) + (100 + 60 + 5)

425 + 165 = (400 + 100) + (60 + 20) + (5 + 5)

425 + 165 = 500 + 80 + 10

425 + 165 = 590
