I think what needs to be reiterated on this video is that, 2 Resistors in Parallel equate to an equation of, Equivalent Resistance (Req) = R1 x R2 / R1 + R2, you're equation is inverted by the time you get to the 10 and 15 ohm. Additionally, this equation can only be used if it is 2 Resistors.. If not, the equation is, 1/(Req) = 1/R1 + 1/R2 + 1/R3 + ... 1/Rn - if there is a resistor in series between the branches then you can't sum them all together.
congratulations, your video has officially made its way into a high-school physics lesson! your comment section will eventually be filled with angsty students saying "*insert class subject here* sucks or "*insert name* was here". have fun! :D
