Concept
Would you call “twenty-seven” abstract and discrete?
Stephen Davies, Ph.D. Version 2.2.2 Through Discrete Mathematics A Cool Brisk Walk / Chapter 1
"Abstract, or concrete? Discrete, or continuous? Abstract, since you can’t see or touch or smell “twenty-seven.” Probably discrete, since it’s an integer, and when we think of whole numbers we think “discrete.” (Food for thought: in real life, how would you know whether I meant the integer “27” or the decimal number “27.0?” And does it matter?)"
