I love math!
Next year I'll be in 6th grade, but I'll be doing 7th grade math!

Why is that, Kyle?

360 = 400 ?

Is it mathemathically possible?

Make an equation using these numbers:  1 2 3 4 5 6 7 8 9 consecutively equal to 100.
Put these signs:  +  -  x  between the numbers.

Example: 1 + 2 +3 + 4 + 5 + 6 + 7 + 8 x 9= 100


Make three more equations.


I just thought of one: 1x2x3x4x5-6-7-8-9=100

Another proof that 2 = 1



I got it Slack.

At the begining it is already wrong because a simple equation should consist of one variable and one constant like A=2 or X = 3, a variable should not be equal to another variable. You may say that a variable is equal to a square of another variable.

In the 2nd to the last line 2(a-x) = a-x (since a = x as the first line, so you may substitute a with x)
So the equation will become 2(a-a) = a-a
Then, 2 (0) = 0
Then, 0 = 0

Conclusion: Our universe is bounded by equations. This means that there's no fixed equation and anything may happen, may change without warning. The universe is unpredictable.

Perhaps the most interesting equation is the Chaos or Butterfly effect (finalized and published by Edward Lorenz in 1961). Initially this theory is not accepted but now, it is widely used in vast fields such as aviation, weather pattern, logistics, production/demand..etc.:

The butterfly effect is a phrase which encapsulates the more technical notion of sensitive dependence on initial conditions in chaos theory. Small variations of the initial condition of a nonlinear dynamical system may produce large variations in the long term behavior of the system. So this is sometimes presented as esoteric behavior, but can be exhibited by very simple systems: for example, a ball placed at the crest of a hill might roll into any of several valleys depending on slight differences in initial position.

The phrase refers to the idea that a butterfly's wings might create tiny changes in the atmosphere that ultimately cause a tornado to appear (or prevent a tornado from appearing). The flapping wing represents a small change in the initial condition of the system, which causes a chain of events leading to large-scale phenomena. Had the butterfly not flapped its wings, the trajectory of the system might have been vastly different.

Recurrence, the approximate return of a system towards its initial conditions, together with sensitive dependence on initial conditions are the two main ingredients for chaotic motion. They have the practical consequence of making complex systems, such as the weather, difficult to predict past a certain time range (approximately a week in the case of weather).

Sensitive dependence on initial conditions was first described in the literature by Jacques Hadamard in 1890[1] and popularized by Pierre Duhem's 1906 book. The idea that one butterfly could have a far-reaching ripple effect on subsequent events seems first to have appeared in a 1952 short story by Ray Bradbury about time travel (see Popular Media below), although the term "butterfly effect" itself is related to the work of Edward Lorenz. In 1961, Lorenz was using a numerical computer model to rerun a weather prediction, when, as a shortcut on a number in the sequence, he entered the decimal .506 instead of entering the full .506127 the computer would hold. The result was a completely different weather scenario.[2] Lorenz published his findings in a 1963 paper for the New York Academy of Sciences noted that "One meteorologist remarked that if the theory were correct, one flap of a seagull's wings could change the course of weather forever." Later speeches and papers by Lorenz used the more poetic butterfly. According to Lorenz, upon failing to provide a title for a talk he was to present at the 139th meeting of the American Association for the Advancement of Science in 1972, Philip Merilees concocted Does the flap of a butterfly’s wings in Brazil set off a tornado in Texas as a title.

You may not like the first step (a=x). But, we do this kind of thing all the time in Algebra. It's true for plenty of a's and x's. Assume that a is the number of ears on my head, and x  is the number of ears on your head. In that case a=x (if a is not equal to x, forgive me for mentioning it).

Kung boring na ang lesson sa Engineering sa una ug dili na maminaw ang mga istodyante, mag istorya dayon ug palamoot ang maestro para pa bibo, labi na to si Sir Lupot sa UB. Pero naa mi maestro sa una nga bahalag nangatolog iyang istodyante basta ma human lang iyang discussion.

Simple Math facts:
  did you know that ......

Even number + even number = even number      8+6= 14
Odd number + odd number = even number         7+3= 10
Odd number + even number= odd number          9+4= 13

Try to discover if this is true with subtraction.

Morag ganahan ko niining inyong discussion da. Mga tricks nga makalingaw sa ulo. Contribute ko niini ha? Simple lang pang hwego.

Prove that 1060=1100.

Here's the trick. Since the above mathematical model is an equation, we have to follow the rule on how to evaluate simple equations. If you add any thing to the left side,  the same thing shall be added to the right side of the equation. Let us see how you can prove this. I need your help.

Check if I'm correct.

370=1320

Let  x  + 370 =1320
 x = 1320-370
 x = 950

950 + 370 = 1320

For those who are interested to know higher mathematics, you may follow the link of the portion of the book I've written in Differential Equations. The particular link covers the section where differential equations is applied in hydrodynamics.

101011011 can be divided by 3, why? because the sum of the digits is 6 divisible by 3.

Rule says,  a number is divisible by 3 if the sum of the digits is divisible by 3.
                  A number with so many digits if the sum of the digits is divisible by 3 , the
                  number itself is divisible by 3.

So the sum of the digits is 6 which is divisible by 3. Then the possible divisor of the given binary number is 3. Tricky!

Bitaw friend, sa akoa kinahanglang gyod ug devotion ang math aron makat unan ang tanang pamaagi unsaon pag solvar sa problema. Ika nga there are many ways to kill a cat. Didto na ko ka realize nga much behind ang Pinas sa math compared to other countries when I took up my graduate and post graduate studies abroad. Makamao ang mga Pinoy pero mas mabagal kay sa iba.

There are 300 feet of chickens and pigs at the same time 108 heads of chickens and pigs. How many pigs ?, how many chickens.

Use quadratic equation.

       x= number of pigs
108-x=number of chickens

To count the total number of feet, we arrive at an equation
4x+2(108-x)=300

Solving for x, we obtain x=42 pigs and therefore
108-x=66 chickens

Check for number of feet
         66x2=132 Chicken feet (daghang adidas?)
    +   42x4=168 Pig feet (daghang pata?)

  Total feet=300

Do we have to use square root? Please show to us.

Layman, you are excellent in Math.
I will share my solution.

1)   x  + Y = 108         ( multiply this by 4)
     4x + 2y= 300

     subtract
2) 4x  + 4y = 432
     4x + 2y = 300
_______________
     0      2y = 132
       
               y = 132 divided 2

                y= 66

               x  + y = 108

               x + 66 = 108

                y = 108-66

                y= 42

     42 pigs and 66 chickens

Mao nay giingon bai nga 'there are many ways to kill a cat'. Mathematical problems offer infinite number of solutions within a multi-dimensional space. Meaning to say that there is a general solution to a problem. From the general solution, there is always the best particular solution available that will suit a particular need.

In example, the equation of a circle x2+y2=R2 is a general solution of the homgeneous differential equation yy'+x=0. From the general equation of the circle you can construct as many circles you can by assigning any arbitrary and real value of R . The real values of R could be infinite. However, if you need only to draw a circle with raduis R=2 for example, then you are particularizing a solution equivalent to x2+y2=4.

Ty for threading this topic. I was not able to  finish my specialization in Math because
when got a failing grade in calculus, I stopped  taking any Math. subjects.

Kon higher Math na , ang akong  solution agpas-agpas na lang.

Moangay man sab ko sa imong mga Mathematrics, which oftentimes mind boggling to me. Kanang mga secrets ang di ko kaapas. Pero they are entertaining.

Balikan to natong akong gihatag nga mental exercise, nga way pa ma solve. Ako na lang ihatag ang solution niini.

Prove that 370=1320.

This can be proven only by using sound. Visayan sound can only solve this problem by just reading the numbers.

370 can be read as three seventy in regular english diction. For the Visayans they commonly read this numbers as 'tre se bente'.

1320 can be read in spanish as 'trece beinte' which sounds like 'tre se bente' as illustrated above.

Have I proven this right? Try giving this exercise to your friends and find out how they will react.
