Describe all the sets and subsets the number 23 belongs to and enter the number corresponding to the correct answer as your response.
There are multiple sets and subsets that the number 23 belongs to. Here are some examples:
1. The set of natural numbers: {1, 2, 3, 4, ...}
2. The set of whole numbers: {0, 1, 2, 3, ...}
3. The set of integers: {..., -3, -2, -1, 0, 1, 2, 3, ...}
4. The set of rational numbers: fractions and decimals that can be expressed as a quotient of two integers (e.g., 1/2, 0.5)
5. The set of real numbers: all numbers that can be represented on a number line, including rational and irrational numbers (e.g., π, √2)
Based on these sets and subsets, the correct answer would be 4. The number 23 belongs to the set of rational numbers.

Find the sum of p and q if p=34 and q=−114. Reduce your answer to lowest terms.
To find the sum of p and q, we simply add the two numbers together:
p + q = 34 + (-114)
= -80
So, the sum of p and q is -80.
