Which is NOT true?

17 = 17
17 = 20 - 3
17 + 3 = 10 + 10
17 + 3 = 13 + 17

1 answer

Let's analyze each statement:

  1. 17 = 17: This is true.
  2. 17 = 20 - 3: This is true, as 20 - 3 = 17.
  3. 17 + 3 = 10 + 10: This is false. 17 + 3 = 20, but 10 + 10 = 20, so this one is actually true.
  4. 17 + 3 = 13 + 17: This is false. 17 + 3 = 20, but 13 + 17 = 30.

The statements that are not true are:

  • 17 + 3 = 13 + 17

So, the final answer is the fourth statement: 17 + 3 = 13 + 17 is NOT true.
