How do you check that 307 + 293 = 600?

Subtract one addend from the sum: 600 − 293 = 307, and 600 − 307 = 293. Getting the other addend back means the sum is right.

How many carries are there in 307 + 293?

2 carries: every time a column added up to 10 or more, its ones digit was written and 1 was carried to the next column on the left.

Is 293 + 307 the same as 307 + 293?
