Question

Write the integer that best represents 23 degrees below zero

Answer 1

23 below zero means you will actually subtract (remove) 23 from zero.
This can be represented using the following expression: 
0 - 23

To represent this as an integer, this means you will use a negative sign to represent the removal or subtraction of the number followed by the number removed which is 23, therefore:
The integer to represent this is -23.

Answer 2

Answer: -23

Step-by-step explanation: 23 degrees below zero is less than zero, which means that it's negative. So it can be written as -23.
