Problem with “Prime and composite numbers intro” [solved]
A learner watching the video “Recognizing prime and composite numbers” in the “Prime numbers” series which is in the “Factors and multiple” category, learns at 0:58 into the video that 0 is considered a whole number.
If they have good memory, they will fail on a question on the review test “Prime and composite numbers intro” which is in the same series.
There’s this question:
Which of the statements are true about composite numbers?
Select all that apply.
-
All even numbers are composite.
-
All whole numbers that end in 0 are composite.
-
None of the above
They will check “None of the above”, because they know that 0, a whole number that ends in 0, is not composite.
The “Show answer” part will say:
“All numbers that end in 0 are divisible by 2, 1, and themselves. They have more than two factors so they are composite. So all whole numbers that end in 0 are composite.”
Which by what they have learned in the previous video is not true.A solution would be to say replace “whole number” with “natural number” in the review test.
