Verify the Vertical Addition: Is 3.05 + 53.2 Written Correctly?

Question

Determine whether the exercise is correctly written or not.

00:00 Determine, is the decimal point position correct?

00:03 We'll use long addition to find the position of the decimal point

00:07 In long addition, the decimal points must be aligned one above the other

00:25 In our exercise, the decimal points are not aligned one above the other

00:28 Therefore, the decimal point position is incorrect

00:30 And this is the solution to the question

Note that the decimal points are not written one below the other. They do not correspond.

Therefore, the exercise is not written correctly.
