Hello /sci/. I'm looking for a good textbook to improve my basic, bare-bones arithmetic. If you have any recommendations please share them ITT!

Something like pic related? What the fuck...
You could shit out a script that autogenerates questions like this, complete with basic gui, builtin solutions and timer in like an hour

Are you serious? What a waste of money that would be. Here is all you need to know.

$a+b=b+a~~~~ a+(b+c)=(a+b)+c~~~~ a(b\pm c)=ab\pm ac~~~~ a * b=b * a~~~~ a(bc)=(ab)c~~~~ a*a=a^2~~~~ a^n*a^m=a^{n+m}~~~~ \frac{a}{a}=1~~~~ \Bigg(\frac{a}{b}\Bigg)^n=\frac{a^n}{b^n}~~~~ \frac{a}{b}\pm \frac{c}{d}=\frac{ad\pm bc}{bd}~~~~ \frac{a}{b} \dot \frac{c}{d}=\frac{ac}{bd}~~~~ \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{ad}{bc}$

Sorry I fucked up my text somehow but you just need to learn the properties and laws of basic algebra which then can be applied to Arithmetic. However don't dwell in it to long it's quite useless unless your goal is to be a human calculator.
