FAQ

What is 906 + 94?

906 + 94 = 1,000

How do you check that 906 + 94 = 1,000?

Subtract one addend from the sum: 1,000 − 94 = 906, and 1,000 − 906 = 94. Getting the other addend back means the sum is right.

How many carries are there in 906 + 94?

3 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 94 + 906 the same as 906 + 94?

Yes. Addition is commutative, so both give 1,000; the column looks the same with either number on top.
