Final answer:
I disagree with Stacey because, mathematically, 23 is greater than 12 not less than it.
Step-by-step explanation:
I disagree with Stacey. According to basic principles of mathematics, the number 23 is greater than the number 12. When comparing two numbers, the number that is greater is the one that has the higher value on the number line, which in this case, would be 23. Therefore, to say that 23 is less than 12 is incorrect.
