[EbuniMisses]

HEY I TRIED 25*25 AND 77*45 TOO AND IT DIDN'T WORK. WHY?

[623236]

This might seem like a silly Q, but y'know, on the second method, where you drew the horiz & vert lines, how exactly do I know where to draw the diagonal lines?

In the States, don't they let you use calculators? Do they not let you use them on the SATs?
