### What in math is an integer?

An integer is a complete number that may be positive, negative, and zero and is not a fraction. Integer examples include: -5, 1, 5, 8, 97, as well as 3,043. 1.43, 1 3/4, 3.14, and other numbers which aren’t integers are a few examples.

### Why is the integer named Z?

The German word Zahlen, essentially meaning “numbers,” is where the notation Z for the collection of integers originates. Positive integers are those that are strictly greater than zero, while negative integers are those that are strictly smaller than zero.

### Briefing:

Given that after a heavy storm, the water level of a river is −3.7 feet. This level is 1/2 times 2.5 feet more than the previous water level.
The previous water level is calculated as,
1/2 ( x + 2.5 ) = -3.7
x + 2.5 = -7.4
x  = -7.4 – 2.5
x = -9.9
