We started walking towards the terminal building.

My office is on the third floor of that mixed-use building.

He was looking for something in the abandoned building.

He caught fish in the river using a fish-trap.

He is a perfectionist, and his approach to work is very strict.

This programming language is said to be Turing complete.

In mathematics, a perfect number refers to a number where the sum of its divisors, excluding the number itself, equals the number.

He is immersed in the study of panmagic squares.

This fish is completely farmed, and no capture is done in the natural environment.
