Are there any communative properties of subtraction because there are many formulas like the slope and distance formulas where you can switch the two terms around right? For example:
Slope Formula: [tex]m=\frac{y1-y2}{x1-x2}[/tex]
You can switch the terms around so that it would be y2-y1, x2-x1 right?
Also for the distance formula:
[tex]\sqrt{(x1-x2)^{2}+(y1iy2)^{2}[/tex]
Btw, the numbers are suppose to be subscripts.
