Answer 3

Closed form of some equations
\[y=mx+b\\
f=ma\\
P=mv\\
e=mc^2\]
open form of those same equations
\[R=mx+b-y\\R=ma-f\\R=mv-P\\R=mc^2-e\]

Answer 4

To write an equation in open equation format, the closed format equation is rearranged with all the terms on one side. The equation is then evaluated to find the residual(R) as above
