Explains variables, systems of equations, Cartesian coordinates, and many other concepts. Fun and educational for all ages.
Math is counting/adding. Algebra is counting with symbols.
All Geometry is triangles. Triangles allow you to define certain useful mathematical relationships, including pi.
Easy to understand explanation of integrals and derivatives using 3D animations.
Close enough is good enough. .999999999999999999999999 = 1.0

Especially when playing horse shoes or with hand grenades.
The upside to being a Rams fan is heartbreak.
Sprinkles are for winners.
Now for something really hard. 😉 Or, counting in different bases. Divide by 2 is base 2[socks]. Divide by 12 is base 12[dozen] or 2 6packs[base 6].There is nothing inherently better in using the base 10 and calling it percents, except it is more universality used.
AgamemnonThe thing inherently better about base 10 is most of us have 10 fingers.
Plus, money is base 10.
Money should be base 5. That is the easiest way to make change. Forget the thumbs and use base 8. 😉
AgamemnonI’ve been through this before, the subtle relentless subterfuge to foist the metric system upon this soon to be great again nation!
Not only that, there is the insidious plot to drive on the wrong side of the road and race around the horse track the wrong way. It all adds up to conspiracy. 😉
Fractions always cause trouble and division. They should be illegal.
Agamemnon360 = degrees in a circle. Why? Because 360 has a lot of factors. 360 – 180/2 – 120/3 – 90/4 – 72/5 – 60/6 – 45/8 – 40/9 – 36/10 – 30/12 – 24/15 – 20/18. That makes lots of ways to divide a circle. That makes certain things easier.
Babylonians used base 60 because it has a lot of factors.
You can use powers. Computer Science uses base 2 and powers of 2. 2 – 4 – 8 – 16 – 32 – 64 etc. Why? Because it starts with ON/OFF switches.Tesla believed in 3’s. Maybe he thought everything was triangles?
Prime numbers don’t seem to make good bases, although base 5 seems to have an exception. Wait, 7 days in a week or 13, a baker’s dozen. lol Forget the prime number conjecture.I should explain base 5 for money. It takes less coins to make change or we could go back to pieces of 8. But, then, we already have quarters, dimes, halves, nickles, and their multiples, base 2 and 4 and 5 and 10, all for one thing.
