Good for you, but don’t think you don’t have to take all the classes that lead up to Calculus You will need to know all thees classes to take Calculus These classes build on earth other If you don’t understand or can’t do the first class you can’t go on to the second assuming you have math skills close to 7th grade here is the progression Pre-Algebra , Algebra 1 , Algebra 2 , Geometry , Trigonometry, Pre- Calculus Calculus 1,2,3 Advance Algebra Differential Equations And more math ..Now not everyone can do this Calculus is the game changer for a lot of people ..If you are really interested in learning math Audit math classes from a university near your Senior citizens can q audit classes for practically nothing

@@johnplong3644 Thanks John! I hope to get to calculus! 2 years. I think your writing is very good and you seem very intelligent. I bet you'll do real well at writing in school and have fun as well.

Thank you! I’m almost 72 and starting a mathematics degree in retirement and this was my first calculus lesson. Absolutely fell in love with it. You are excellent!
Greetings from the BIG SKY. I was learning multiplication and division in 7th grade. Probably around 1960 at the time. It wasn't till college that I saw a calculus integral sign for the 1st time.
x and y are the arbitrary names (better to call it a convention or definition) given to the orthogonal (perpendicular) axes in the cartesian 2-d plane, By definition x is the name given to the horizontal axis and y is the name given to the vertical axis. A point in the plane can be labeled by two coordinates which we also label (x,y), this is suggestive. To locate a point in the plane such as (3,2), locate the origin point and then translate that point as follows along the x direction first and then along the y direction. i.e. use the first coordinate 3 to tell you how many units to move horizontally along the x-axis, and then use the second coordinate to tell you how many units to move vertically parallel to the y axis, here 2 units. Your destination is the point (3,2). Finally we are interested in points (x,y) that satisfy y = x^2. The totality of these points we call the graph of y = x^2, and it traces out the shape of a parabola curve. The integral problem is to find the area under the curve of the graph of y = x^2 (but above the x axis), from x =1 to x =3.

You can get to calculus in less than 2 years

Thank you! ... It was clear and understandable.

Why does Y equal X squared? That seems arbitrary.
X^2 is actually X axis.... therefore Y axis is acually X^2....the graph is showing X axis n Y axis only..
x and y are the arbitrary names (better to call it a convention or definition) given to the orthogonal (perpendicular) axes in the cartesian 2-d plane,
By definition x is the name given to the horizontal axis and y is the name given to the vertical axis.
A point in the plane can be labeled by two coordinates which we also label (x,y), this is suggestive.
To locate a point in the plane such as (3,2), locate the origin point and then translate that point as follows
along the x direction first and then along the y direction.
i.e. use the first coordinate 3 to tell you how many units to move horizontally along the x-axis,
and then use the second coordinate to tell you how many units to move vertically parallel to the y axis, here 2 units.
Your destination is the point (3,2).
Finally we are interested in points (x,y) that satisfy y = x^2. The totality of these points we call the graph of y = x^2, and it traces out
the shape of a parabola curve.
The integral problem is to find the area under the curve of the graph of y = x^2 (but above the x axis), from x =1 to x =3.

What seems arbitrary?
Thankyou for this
By the way i am a real 7 th grader and want to make my parents proud studying calculus 😊
That is never gonna happen 😢
Thank you for making this video! I now understand calculus in this area better.
P.S I’m a 5th grader believe it or not.
Me too but i am a real 7th grader 😂
I’m in 6th now

It is very simple ,, yess a 7th graders can easily solve it if he knows the formula, but he won't be able to understand what does it means ..
