How to Read Math

Baffled by equations, well no more! Continue learning at this video's sponsor brilliant.org/dos
Lots of people find mathematical equations intimidating because they don't make sense. But they are not hard to understand if you follow a few steps, anyone can learn to read them. And it is well worth it because they are so incredibly useful to describe everything in math and physics. If you already know I'm sure you know someone who might like this video, I'm going to send it to my family who are less mathematically inclined than me.
The steps you need to know are: 1. Find the variables, 2. Work out what all of the different mathematical symbols mean, 3. Wok out what order you would perform the mathematical operations if you were going to plug numbers in to the equations. These steps really help you get your head around what an equation is telling you. Also, don't be scared about the greek letters, they do just the same thing as normal letters, they either represent constants or variables.

Oh, how I wish I had this explanation back in the Seventies when I was in Highschool. It would have saved years of anguish. So clear and informative. I can remember the horror of trying to make sense of Letters suddenly appearing in Sums and the pain it caused me. Bloody dreadful teachers back then, probably got off with a power trip of superiority of knowledge over us ordinary kids.

[@planktonfun1]

I don't know why educational facilities don't bother to make visuals as everyday learning material. they like to encrypt things and hope that we unencrypt them and learn it. its an inefficient learning process given to what technology we have today.

[@iwillmakeit821]

Hieroglyphics

[@shivam5105]

But the process of understanding and internalising the so called “encryptions” is the true beauty of maths and science, the visuals can come later to understand the physical meaning of what you are doing during maths, a great example of this is 3blue1brown, because when you are working with maths and science in industry or in academia, the problems aren’t so available in visual format, you have to understand what the problem is asking and try different techniques to figure out, and you would only be able to use these techniques if you made an attempt to understand and internalise them yourself instead of being handed everything on a platter

Yeah. They always teach it as seemingly vuagely and unhelpful as possible. They'll just keep repeating what essentially ammounts to "why can't you do it? It's easy! Let me do it for you to show you that!" Without actually bothering you explain WHY or HOW and we're expected to just immediately understand what's going on with no real explanations.

[@fancymcclean6210]

I wish I had studied more mathematics at uni. When I first studied calculus it was a revelation to me. As a biologist, we didn't have to do a lot of at undergrad level however, I opted for a calculus course in my first year. I don't think I was a natural mathematician, but my grades were very respectable. I'm sure I could have studied physics or mechanics- don't know why I didn't- mayhap my love of genetics was too strong. Anyway, on the strength of this vid I have subscribed.

Step 4. Make sure you are comfortable with your calculator. I know with mine depending on whether I'm entering degrees, radians, or gradient I can switch between those modes. If I want decimal notation then I set my calculator to approximate and if I don't want decimal notation then I set it to exact. Just make sure that when you enter in the values it conforms to the order of operations.

That's was a simple, yet surprisingly effective starter on "How to Read Math." That is impressive, I probably would have touched on Trigonometry (and a few of its applications) rather than calculus in the way you did, I would encourage you to add trig rather than replace calc with trig. For me personally, obtaining a good grasp of Trigonometry was the most difficult and most confusing part of understanding Calculus and and going further. Trig is one of the simplest* and one of the most important areas of mathematics I've come across after algebra. I do not use calculus as much as I thought I would, with electric motors and the type of robotics I work with and play with, a solid understanding in Trig makes everything else so much easier.

Although I usually appreciate your videos very much, I have to say that this particular one was unusually superficial and contained very little actual information. The topics that were tackled were on the one hand extremely elementary (know what the symbols in an equation represent and keep the order of operations in mind), but on the other hand the actual mathematical concepts that are applied were not tackled at all (What is an operation/a function? What does it mean to 'solve' an equation?). Even if I were not able to properly read basic equations, I strongly assume that this video would leave me non the wiser. Also, the narration sounded pretty disinterested and it was not very focused (see 'cheat sheet' and 'calculus' parts). Maybe I just wasn't part of the demographic this time. Nevertheless, I hope that this criticism was constructive and useful. Keep up the good work!

Great video. I watched it because I'm in Australia, and we tend to say "maths", as you do in the UK. I was curious to see how you would say it - and it looks like you avoided it. Clever and considered. Looks like you've spelled it the North American way for broader appeal, and I guess I get that.
