[@randomidiotonline5072]

Most likely because the videos work at a different pace, and only do one or two problems. In lessons, teachers tend to do several upon several questions, slowly helping you lose focus throughout. Well, that's my own experience and opinion. Maybe it's just because Khan academy is prerecorded, easily accessed, and you can skip time ahead as long as go back.

[@polygames4712]

Showing the logic of why you do something in math makes such a huge difference. I don't understand how anyone can learn math in school it was just like now we do this following order of operations without explaining why so as soon as I encountered a problem that wasn't covered in the practice or mixed different concepts I wouldn't be able to figure it out

[@milady1377]

all these people talking about how their teacher doesn’t even make sense, for me my teacher doesn’t even do the video herself 😆

[@tashmeebs]

This vid seems to be way more complicated than it should be... What I learned was to get all the X variables on one side and all none variables on the other. In other words, subtract the 5X from the right to the left, creating a negative 3X, and subtrating 3 from the left anf moving it to the right. Then you have negative 3X equals negative 5. When you divide the neg. 3 from the X, you get the answer: 5/3. It's real simple. Just remember to get all variables on one side.

[@mrhoolagan]

what program does he use to write all the stuff

[@grenenamek7669]

if x=5/3 we can check our work by multiplying 2/1 and 5/3 which equals 10/3 then adding 9/3 this equals 19/3 or 6 1/3. on the second half of the equation we do the same. 5/1 multiplied by 5/3 which equals 25/3. we then subtract 6/3. this will equal 19/3 or 6 1/3. this is how we can check our work on this equation.

My equation is: 2m = 24 + 3m I'm confused because of the single number on that side do I add?

[@TheJoey3590]

Just solve for m. There are different ways to approach this equation. The most simple way would be to subtract -3m to the other side so it becomes -m = 24. From here, it becomes m = -24. Another way would be to subtract 2m to the other side with 24 + 3m. Therefore the equation becomes 0 = 24 +m. The last step for this way is to subtract the 24 to the other side, giving you the answer : m = -24. The whole process involves trying to get the variable on one side all by itself.
