 May11 asked 2 linear systems: same solution set implies row equivalence; how to prove? May10 answered Intuition in algebra? May6 comment Integer combination of $V\subseteq\mathbb{Z}^n = (1, 1, 1, \ldots)$?Well, thanks anyway all. May6 revised Integer combination of $V\subseteq\mathbb{Z}^n = (1, 1, 1, \ldots)$?tried to make it a bit clearer May6 revised Integer combination of $V\subseteq\mathbb{Z}^n = (1, 1, 1, \ldots)$?add clarification May4 revised Integer combination of $V\subseteq\mathbb{Z}^n = (1, 1, 1, \ldots)$?added 68 characters in body May4 asked Integer combination of $V\subseteq\mathbb{Z}^n = (1, 1, 1, \ldots)$?

Apr28 asked Visualizing identity $m\le3n-6$ for simple connected finite planar graphs Apr27 revised Formalizing the “fitting together” of objectsadded 95 characters in body Apr27 comment Formalizing the “fitting together” of objectsOkay so define the cube as $-0.5 \leq x,y,z \leq 0.5$ and square pyramids $z \leq x,y \leq -z$, $-z \leq x,y \leq z$, $-x \leq y,z \leq x$, $x \leq y,z \leq -x$, $-y \leq x,z \leq y$, $y \leq x,z \leq -y$. Now I'm trying to see an easy way to show that any point $-0.5 \leq a,b,c \leq 0.5$ is in one of those.
