And for those who are wondering why this order of connecting and disconnecting matters: it's for safety. Obviously for the actual starting of the car it doesn't matter, as long as the polarity is correct, but it does matter for your safety. You connect the positive first because if the risk of short-circuiting the live battery. When you connect the positive lead the most common mistake is that you accidentally touch the positive lead to the chassis of the dead car. If the negative of the dead car is already connected then the entire chassis of the dead car is also connected to the negative of the live car and you have a short circuit. If you leave the negative off then touching any part of the dead car with the positive lead has no effect and when you connect the negative the only way to get a short is if you literally connect the negative lead from the live car to the positive lead on the dead car and that's not a mistake that people make. The reason why you disconnect the cables from the live car first is that the dead battery is now charging and when batteries charge they can release gasses that are quite flammable. Disconnecting a live wire can produce sparks and you do not want sparks to happen in an engine bay where a battery is letting out little flammable farts. The more you know.
