Turns out Abraham Lincoln was the kid happily working extra long division—and honestly, I love that. These are his actual subtraction and division problems, done by hand on the frontier with almost no resources. Self-taught, stubborn, and exactly the student who would’ve been in my math class asking for one more problem. Log cabin homework to the White House… not a bad trajectory for a math kid. #AbrahamLincoln #MathLover #MathTeacher #PresidentsDay
