Divisible by 7
Chapter 1 when you are trying to simplify fractions, chances are you are having a hard time, you don't know what to factorize. Here are some of the techniques to know if a number is divisible by a simple factor, say from 2 to 9. Note that we are going to deal only with base-10. These tests can be divided into 3 types : Dividing Carries, Digit Sums & Complex Equations Type 1: Dividing Carries the main idea is that some factors can divide some power of ten perfectly, so we don'

"Why are you so smol ?"
Starting from March 2021, I played VRChat until now, the avatar I use as my normal virtual form is a Kon, a short cute HalfHuman Half-fox character designed by Midori. Because of that, I am short to other users with average height, sometimes other players just walk to me and asked: "Why are you so smol ?". And I will reply to them: "Everything here is relative. Size is relative, time is relative. There is nothing which is the biggest, only bigger; there is nothing is the smal

I can walk 5 seconds in a second
One day I assigned a question to my students : If Aaron can walk 1.2 meters for each second, how long will it take for him to walk 25000cm. And the next lesson we discussed the question, and I asked them "how long the distance Aaron can walk within a second ?". I was expecting them to say "1.2 meters" since it is so easy and it is stated directly in the question, but instead, one of them said 250seconds". Of course, I have to correct them, but after the lesson, I think to mys

Approximation of Pi (π)
M2007U-E2016-A2017-S2017-M2021_SMT-20160929x01 Let's draw a circle with a radius of r, and install a polygon inside it. As the number of the sides of the polygon increases, the polygon is approaching a circle, but the polygon will never be a circle. cutting the polygon into several equal triangles with one of their tips at the center of the circle, let's call the angle between 2 radii as θ. as the side of the polygon increases, the angle θ becomes smaller and smaller, the

Sine Circle
M2007U-E2016-A2017-S2017-M2021_20180508x01 Let's draw a circle with a radius of R and mark out all the angles with a factor of 5 degrees around the circle as the diagram shown on the right. now let's mark out all different radii with a length of (R x the sine of the angle the radius is pointing to) from the center. you'll find that the tips of those radii are likely to form a circle, the target of this article is to prove that the tips of the radius are really forming a cir

Then add the number "0" to a new row at the bottom of the matrix and aligned to the last column. Feature for the multiples of the Factor F which are smaller than 99, the numbers of Tens which are inside a certain column in the matrix will point to the numbers of Ones which are inside a

二 or 两 or 双 or 对 ?
If you came from Facebook, welcome. If you are here directly, maybe you are learning Chinese.

1) Drizzle So little amount of raindrops that you don't even need an umbrella. Just like a spray~ nice and soft~ 2) Sprinkle Slightly heavier than a Drizzle, this can be used to describe snow as well. Just like sprinkling sugar on a cupcake. 3) Shower Ok, you can get wet with this, so you need an umbrella, although the duration is short. 4) Thunderstorm Raining heavily, and the area is enormous, you may hear thunders as well. Although it sounds scary, the duration is short. P
