Answer:
The integer representation of 30° below zero is -30.
Step-by-step explanation:
To represent a temperature below zero, one simply needs to use the subtraction operation in math.
With 0 as our reference point for temperature, let's subtract 30°. This is done because subtracting a number from zero gives us a negative number, which is how we represent a temperature below zero.
Let's start with zero. From this, as stated, we want to subtract 30.
Written mathematically, this is: 0 - 30 = -30.
So, the integer representation of 30° below zero is -30.
