Question

Jasmine wrote that 4+2.6=3. Use the drop-down menus to explain why 3 is incorrect.

Answer 1

Answer:

It is incorrect because 4+2.6=6.6

Answer 2

Answer:

You have to align the decimal points. Imagine 4 as 4.0 and add

 4.0

+ 2.6

_____

  6.6

if you misalign the decimal points then your answer is wrong.

If it was 4.001+2.6 you would still have to align like shown below

4.001

+2.6

_____

 6.601

The decimal points have to be aligned.

If you commented the dropboxes I could help with them.
