Luis Ramos Soto can’t stop worrying about math.
With the biggest test of his 11-year life looming, he hasn’t yet mastered how to solve algebraic equations or find the length of a triangle’s hypotenuse. He hadn’t learned either one at the James W. Hennigan K-8 School in Jamaica Plain, but both are likely to show up on the test.
Over the last three months, Luis has pretty much given up his PlayStation. And YouTube, once an oasis of comic relief, is now reserved for instructional videos about math.
