Rajon Rondo is one of the NBA’s finest pure point guards. He analyzes the defense, sizes up its variables and chooses the quickest and most effective path to earn points for his team. He orchestrates the movements of his teammates and adjusts his plan of attack in response to subsequent variable reorganization. He doesn’t plow ahead with brute force, but calculates an optimal strategy for basket-making and frequently succeeds in the execution of that plan.

Earlier this morning, Rondo took these skills of manipulation to the classroom, teaching algebra to a high school math class at Jeremiah E. Burke High School in Dorchester, Mass. (Picture evidence above). Why these kids are in school on election day is an entirely different head-scratcher, but we tip our cap to Rondo for brightening their day (and hopefully teaching them something, too) and giving hard working Ms. Oshodi a moment to relax on what should have been a day off.

We just hope that Rondo knows what he’s doing. Although his professional skills are not dissimilar to algebra, let’s break down the sequence of equations on the board just to make sure he can handle himself. In case you can’t see, it reads as follows:

3(x – 7) + 5 = 26

5x = 70

I think someone forgot to show his work. It should have looked like this:

3(x – 7) + 5 = 26

3x – 21 + 5 = 26

3x – 16 = 26

3x = 42

x = 14

Although Rondo seemingly would arrive at the right answer since “x” in “5x = 70” equals 14, we’re not really sure where he got the “5x” or “70” from. Then again, it’s been a few years since we’ve done any serious algebra.

Maybe this is a sequence of equations or two separate problems entirely that just so happen to be aligned in sequential form, so we won’t jump to any conclusions. But if he really did screw up, he probably shouldn’t have tweeted a photo of it.

And while he’s at it, he might want to give Ray Allen a math lesson for free. Miami and Boston gave him competing offers this past summer, but he seemingly stumbled over the simplification of terms. So here ya go, Ray.

2 x ($6 million) > 2 x ($3 million)

$12 million > $6 million
