Algebra practice question

How many integers x satisfy both x ≥ −2 and x < 3?

Answer: 5

The integers from −2 up to but not including 3 are −2, −1, 0, 1, 2 — five of them.

Common wrong answers

If you answered 4
4 misses x = −2, which the ≥ allows.
If you answered 6
6 counts x = 3, but x < 3 excludes it.
If you answered 5.5
The count of integers must be a whole number.
