Calculate using expanded notation, showing steps. 72 + 806

Question

Did I do it right?

72 + 806
(7*10) + (2*1)
+ (8*100) + (6*1)
=(8 * 100) + (7*10) + (6*1)

Answer 1

Good grief!
What is happening to the educational system???
72+806=878

Answer 2

That was rude and uncalled for! It asks for expanded notation.

Answer 3

Bart: You missed Dr Reiny's point. You did not add the two numbers correctly. In the units place, 8 is the correct digit, not 6.
