Helping students to develop math fluency takes more than just flash cards. It requires teaching them how to think about ...

19 is only 1 away from 20, so you prefer to start by multiplying 20 times 5, which equals 100. Then we need to take away a squadron of 5, because there are actually only 19 squadrons, not 20. 100 take ...

Having them lined up like this makes them easier to count. You've got four rows of meebs, with 3 meebs in each row. So all together that's 4 times 3, which equals 12. From where you're standing you ...

Abstract: A method to recover the unknown sparse error e in a corrupted linear system b=Ax+e is proposed. The original problem is first transformed into a convex ...

Abstract: This study focuses on a reduced-order extrapolation method for the coefficient vectors of the mixed finite element solution for two-dimensional fourth-order hyperbolic equation. We first ...
