Estimate the sum of 703 and 620

1,320 Is my best guess because I know thAT 700+600 is 1300, 3 can be rounded to zero, which leaves 20 left. So a good answer would be 1,320.

*Rember there is not a right answer, there can be a couple different answers, as long as it is close to the sum

I think 1323 is the sum
