Well, I'm just curious about different things people are learning in different country and grades. Welcome to reply.

This is a math problem from the high school entrance exam ( for 9th graders ) in my city 2021.
In the plane rectangular coordinate system, the vertex of the parabola y = 2 (x-m)^2+2m (m is a constant) is A
(1) When m = 0.5, write down the coordinate of point A and the coordinate of the intersection of parabola and Y axis;
(2) If point a is in the first quadrant and OA = √5, find the expression of the quadratic function corresponding to this parabola, and write the value range of X when the function value y decreases with the increase of X;
(3) When x ≤ 2m, if the minimum value of function y = 2 (x-m) ^2+m is 3, find the value of m;
(4) Make the vertical line of the Y axis through points P (4, 2) and Q (4, 2-2m) respectively, and intersect the symmetry axis of the parabola with points m and N. when the parabola y = 2 (x-m)^2+2m has two intersections with the edge of the quadrilateral PQNM, record the two intersections as point B and point C respectively, and the ordinate of point B is greater than the ordinate of point C. if the distance from point B to y axis is equal to the distance from point C to X axis, write the value of M directly
Now I am learning machine elements on mechanical engineering. İt is very hard to learn this lesson which Most of mechanical engineering students is nightmare.
I am learning hungarian! Just for fun and for holidays! Oh this language is rock hard to learn, but fun! Szép hétvégét és üdvözlet! (= Nice Weekend and many greetings!) 😃
I'm learning French
This is a math problem from the high school entrance exam ( for 9th graders ) in my city 2021.I'm in eighth grade. I'm learning first-order functions, root symbols, Pythagorean theorem. Physics includes mechanics and mass

Japanese, I'm still learning Kana characters, and began using some Kanjis like sun, day (Nichi, Jitsu, hi) and moon, night (Gatsu, hon). It is funny for me to learn a new language.
