Not really third grade. Algebra can be a pretty mind blowing subject when you first hit it, so its generally taught with really "actual maths" until people get the hang of letters and the like.

the pairs of equations form a linear system. You equate variables: for the first pair you might do {y = 9 - 3x , y = 7 - 2x} , giving you { 9 - 3x = 7 - 2x} , then you rearrange it a bit to give a value for x, and sub that into one of the equations to get a value for y.

Are you dumb, those are pairs of equations, you have two variable and two equations, solve for one variable in one equation and substitute that term into the other equation, then you only have to solve for one variable. So you'll get an answer for one variable then all you have to do is plug it in to the other equation. It's really simple stuff.

They should teach more advance math to younger kids but they're can't because "hurr durr the schools have to let the slow kids catch up."

If the kids don't understand the advance math then they should stay after school and take tutoring sessions until they get it so they're prepared for the next day. But that would require extra effort from the school itself and the old teachers who just come for their paycheck would bitch.

I remember becoming suddenly enlightened around the age of 16 when I started doing A level maths. Until then, I passed tests but I never really understood what I was doing.

It was only when I started on my A levels that I realised, or should I say *understood* that the '-5' in , say, 8-5 was a term itself, and not "8 and 5 with a minus operation". I only really understood *why* I was solving equations for x^2+x+1 = 0 at this point, before that I never really understood where the zero came from.

I never really understood the rules behind algebraic manipulation until this point, either: I'd try to multiply both sides of an eqation by 2, but end up only multiplying one of the terms on either side (Id change 1 = x + 3 into 2 = 2x + 3, say) but then I would understand why sometimes I could do this and other times I couldn't (for instance 1 = x*3 going to 2 = x*6 is valid.) Looking back, I was pretty dumb when I was a kid, actually.

Its strange how little it is possible to understand about maths while still being able to get A grades in your tests.

Schools in Florida have a program allowing students to skip up to two years in math when entering middle school and to take double math in high school(going to college early for extra math if necessary).

For example, a student can take pre-algebra through geometry in middle school, Algebra 2 and Pre Calculus in 9th grade, AP Calculus(1 and 2) in 10th grade, Dual enroll and take Calculus 3 and Statistics in 11th grade and take Linear Algebra and Differential Equations in 12th grade.

Sadly, most students are struggling with Algebra 2 in 12th grade and taking Pre Cal in college(if they go). Also, students taking math beyond Calculus is frowned upon by Ivy League schools.

just cause the Asians chug math down their kid's throats at early ages doesn't make their education systems better. They sacrifice other things for it - Japanese students aren't required to take Geography or World History, EVER. Not only that, their classes are heavily government based as well, only to the point where teachers have little to no room for unique classroom experiences. It's like an army of clone teachers trying to breed clone students, which as a collectivist culture makes sense.

Honestly, even as an Engineering student, if I had to choose between taking Calculus 2 years later or forsaking history all together, I'd have to wait on the math. In today's world I just cannot comprehend why any education system would knowingly produce students ignorant of not only their own culture's history (most Asian countries also neglect teaching their OWN GOD DAMN HISTORY! I know South Korea sure did when I lived there, I bet China does, and from what I've heard from other military brats Japan sort of does), but those of the world as a whole and its affairs.
