Solve and Draw

The top-left corner square is (0, 0). The bottom-right corner square is (9, 7). Fill grids by clicking. Clear drawing by refreshing the page.

• Draw a hollow rectangle with corners coordinates at ($a$, $b$), ($c$, $b$), ($c$, $d$), ($a$, $d$).
• Fill points ($c$, $e$), ($b$, $f$), ($b$, $g$), ($e$, $a$)
• Fill points ($d$, $e$), ($d$, $f$), ($d$, $g$), ($h$, $a$)
• $a$, $b$, $c$, $d$, $e$, $f$, $g=5$, and $h$ represent 8 different one-digit numbers (0~9).
• $b^3(b+e)=g^2-e$
• $(d+f)h=d(f+h)+f=a+(c-d)^3(2c-d)$
