If you watched MTV in the early 2000s you may remember a fake boy band called 2ge+her which had a "hit song" Calculus. That song tried to simplify the term Calculus by saying "I know my Calculus cause you plus me equals us". While that could be considered a calculation, calculus is just a bit more complex than that.
Calculus is a mathematical understanding of changing values that relate to a function. It is because of this that sabermetric stats use a form of calculus to look at different values of baseball.
Baseball cards as we know them in their current Topps format began with 1952 Topps.
We are all familar with the design as Topps has used it many times over the decades since it's original release.
The back perfectly captures the original card backs and statistics shared. Pretty simple calculations for hitting and fielding.
Things changed in 2015 when Topps began to insert different card backs known as sabermetric backs.
These included stats like Onbase Plus Slugging, isolated power, weighted runs created, Wins Above Replacement, and percentage of walking or striking out.
These stats have become common talk among "newer" fans of the game who look at statistics beyond just batting average and Runs Batted In.
As you can see on the card back, Cutch is still way above league average in many of these categories. Remember he got injured early June 2019 and missed essentially 4 months of the season due to a torn ACL.
So there you go, a changing value of using integers to calculate a player's worth. Sounds similar to calculus to me, so I guess I passed this exam.
