FAQ

What is 136 + 71?

136 + 71 = 207

How do you check that 136 + 71 = 207?

Subtract one addend from the sum: 207 − 71 = 136, and 207 − 136 = 71. Getting the other addend back means the sum is right.

How many carries are there in 136 + 71?

1 carry: 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 71 + 136 the same as 136 + 71?

Yes. Addition is commutative, so both give 207; the column looks the same with either number on top.
