As the universe expands, #expanding #space is said to "stretch" photons. But if it stretches photons, does it also stretch molecules, galaxies and you? A portion of this video was sponsored by Salesforce. Go to https://salesforce.com/veritasium to learn more.

You may think you have free will and can choose what you do, but this might be an illusion. Your body is made up of particles that
blindly follow the laws of physics, with every outcome already predetermined. So, you might not have any free will at all.
Is free will an illusion, or does it exist? Which philosophical camp is right?

In this video you will learn how to read maths symbols and equations in English and improve your maths vocabulary ( or math vocabulary). You will learn how to read addition, subtraction, multiplication and division equations as well as how to read equations involving brackets, fractions, decimals, square roots and the exponents. You will also learn how to read “greater than”, “smaller than” “is not equal to”, “greater than or equal to”, “smaller than or equal to” or the “approximately equal to” signs and many more ( ≈ ÷ ≠ √ ≤ ≥ × - = + ). You will also learn the difference between math and maths, two short forms for mathematics. There is a test at the end so stay tuned.

Since the days of Ancient Greece, philosophers and scientists have been wondering: What is space? Is the absence of things… a thing? These questions continued to fascinate physicists in the modern era, leading Isaac Newton, Ernst Mach, and Albert Einstein to wonder about the true nature of the fabric of the cosmos. The search for an answer led them to some of the greatest theories in physics. This week, we ask if space and time are really real, and how they come together to make “spacetime”!

Improved math is a channel created to provide additional instruction on essential math concepts. I’m passionate about math and I know first-hand how important math concepts are in the real world.

Teachers, parents, guardians, homeschoolers, and students can use these videos to help reinforce math skills. These math videos are designed to help teach yourself math or provide self-study math tools to assist when additional instruction is needed. Teaching math and learning math has changed the way many students learn in this virtual environment. Having on-demand math videos can provide math tutoring needed when children are not able to get help from their teachers after school hours or when trying to do math at home.

The library of math tutorials that I create can also be used as supplemental instructional material for homeschool math. Each full-length video comes with a subsequent knowledge check or math practice problems which serve as a virtual math topic worksheet to test your understanding of each skill. These videos can be paused to work out the problems on your own, then unpaused to check your answers. All of these videos can be found under the Knowledge Check playlist.

I also have a library of shorter videos (less than 1 minute in length - shorts) that are quick math tips and tricks on basic math topics. Some of these short math help videos include problems that you can work on yourself and submit your answers in the comments. They are all listed under my Math Tips and Tricks playlist.

Improved math is creating more videos every day to cover topics from 4th grade, 5th grade, 6th grade, and 7th-grade math. The videos focus on fractions, basic math operations, geometry, and ratios but more topics are being added all the time. If there is a specific topic you would like to see covered, drop me a comment in one of my videos and let me know!

Free math help videos will be posted every Thursday and Friday. For additional math resources, check out my math help website at improvedmath.com where I post math worksheets and answers along with additional context on math basics.



Thanks for watching my channel.

This video goes over everything you need to know to add mixed numbers.

Improved math is a channel created to provide additional instruction on essential math concepts. I’m not a math teacher, I’m an accountant. I know firsthand how important math concepts are in the real world.

Teachers, parents, guardians, homeschoolers, and students can use these videos to help reinforce math skills.

Hi! Welcome to Improved Math!

If you want to learn to multiply multi-digit numbers, then this video is for you.

Understanding basic math isn’t just about crunching numbers; it's about fine tuning problem-solving abilities, making informed decisions, and gaining deeper insight into the world around us. From everyday tasks to complex situations, math plays a pivotal role.
