" Five apples are an instance of the number 5 "  no, it is a count of 5 apples  an "instance" is just the 5 written or displayed
"...a pair of shoes is an instance of the number 2,..."
no, it is one ( 1 ) pair not two,  and it is a count, not an instance of the character indicating a 2 .
Why are you posting such selfdefecating posts filled with intentional errors ?
