Subitize or sight-count

One can say "I eyeballed the tanks" to indicate that you made an approximate count or assessment visually. Between "tallied" and "eyeballed," the term "eyeballed" is more informal and implies a less precise estimate based on visual judgment. "Tallied," on the other hand, suggests a more systematic counting, even if it's just an estimate.

So, if you want to convey a casual and quick visual estimate, "eyeballed" would be the better choice. If you want to imply a bit more of a methodical approach to your estimate, even if it's not exact, "tallied" would be more appropriate. Both are correct, but the context in which you use them will determine which is better. For example:

- **Eyeballed**: "I quickly eyeballed the number of tanks in the lot."
- **Tallied**: "I tallied up the tanks to get a rough idea of how many were there."

Take a gimpse at sth means to have a very quick look that is not very clear just helping you to understand sth.q
