Monster Equations!


When I first look at these questions, I think, yeah right, I can't do either one of these... but as soon as you start breaking them up into parts and looking at it separately, it becomes easier.

1a) First you put all of the negative exponents on the reciprocal top or bottom so that they are positive.
b) Spread out the 5 over 2 to the entire equation.
c) Solve each root separately.
d) Make sure they are in their simplest form!
Answer) Write down your answer and put it in a box so it is noticeable!

2a) Change the roots to x over y as exponents of the number.
b)Solve each section of the equation separately.
c) Take out any common numbers to put in simplest form
Answer) WRITE OUT YOUR ANSWER!

I don't know how to use the Word Equation something-something, so, I hope this helps anyways!

What does it mean to be good in math?

Today in Math class we were trying to find qualities that would make a person good at math!
We came up with a long list and now I have to pick three of the ones I think are the most important. These are the three - hard working , willing to learn and you must have perseverance .

You must be hard working because in order to solve a problem, sometimes you have to keep working at it - sometimes longer than you want to. When you don't understand something, you can't give up and forget about it, you have to keep trying to find the answer. Whether it's looking at the question in a different way, or going back to the basics of the question - you have to find it! Else it will bother you for the rest of your life!

Being willing to learn is a very important characteristic in math because there is ALWAYS more to learn. Math keeps going and you can't just want to stop after learning a certain amount... you have to want to learn more. You also have to be willing to learn from your mistakes. It's not a bad thing when you make mistakes because the next time you come across that question, you'll remember the mistake you made and you'll remember how to do it properly.

You also must have perseverance. This is obvious, because you can't just stop in the middle of a question because you don't know what to do - look back over your work, see if you did anything wrong or can do something differently

Problem Solving Set #1


On February the 9th my class recieved a worksheet to finish for homework. Sadly I did not get 100%, but they say that you learn from your mistakes, so if you never make a mistake, you won't learn.


So, the question I will go over is #11. Twelve balloons are arranged in a circle as shown. Counting clockwise, every third balloon is popped. C is the first one popped. This continues around until two unpopped balloons remain. The last two remaining balloons are: (A) B, H (B) B, G (C) A, E (D) E, J (E) F, K


Starting at C, you cross out every third balloon clockwise. It should be in a pattern like this: C, F, I, L, D, H, A, G, B, K. Once you get to K, you should only have 2 balloons left: E and J!
This is the only way I know to solve this problem and it's really easy too! When I was solving it I wanted to play MASH!
So, I hope now you understand this question and it all makes sense to you !

Tower of Hanoi


Describe the strategy and the formula for the puzzle: Tower of Hanoi


When I first played this game, I used the method of guess and check ... but after I got to 5 disks and couldn't find an answer, I got incredibly bored and frustrated .

Seeing as I couldn't find a mathematical solution , I'm still currently using the lovely method of guess and check!:)

My picture above proves to you that I have beaten 5 disks and if you can't do this then maybe my next piece of information will be helpful! All I've found out so far is, if you have an odd number of rings , you have to start by putting the smallest ring on the furthest pole and the second smallest ring on the middle pole. For an even number you would need to reverse this - putting the smallest ring on the middle pole and the second smallest ring on the furthest pole.

I don't know how else I can help except, don't give up, because it's problems like this that we're happy to solve! I can tell you I was... after looking at a few hints... But anyways, DON'T GIVE UP! One of the first rules in math, you are not allowed to say "I can't," because else we'll have to kick you out!
