When make this post I believ that I am still normal and not crazzy. Not because a week does not posting in this blog or lost memories. It’s not because a week write math book, making it its own problems and continue to be in the mind and will forget myself. Look at the post title above. Title is not over when one or just want to search only sensai.

Let’s look the proof …
When we child small, your teachers teach you that 1 + 1 = 0. because you believe you can not avoid, and with your teacher to prove things simple. For example, there is 1 cow and the cows have 1 more, so note that there are two cows. It is true, and of course at that time did not want to sign a mathematical proof is not it? Because you still small, and let alone believe it passed. Create a thought what if it will only meet the mind and make you stress.

In the field of verification of a mathematical theorems is normal. In principle, a verification is to prove theorems segment with the same left-right segment if it proves an equality and the implications of a note where antesedennya and with the steps in the right, logical and systematic so that impact correct. Add a confused is not it?

While still a student I never taught how to prove 1 + 1 = 0 with the theory of the collective. Of course this time I do not want to prove that 1 + 1 = 0. However, on this occasion, I want to show the other side that read “one kaprah” (one considered correct) where 1 + 1 = 0. Kok bisa? Verification with the simple and not based on theorems that are difficult to use or hard-set theory and number theory. You only need a bit of knowledge:

1. We have that  i =sqrt (-1), i : complex number
2. And also that (a x  b) = sqrt (a) x sqrt (b)

It’s simple ? Let we look the proof:

It’s easy ? Well, according to the above verification is a verification error. Although a logical, systematic look correct, but there was a wrong step. I do not want to teach you something in the wrong or upon you, but let us try to see the other side of a matter, not only see things from a certain perspective.

In addition, the evidence above also teaches us to always sensitive and critical of everything that is around us. Not only accept it so what is going on and become a habit in our lives.

I don’t responsible for all consequences of this post

Step 2
Find out, what am I supposed to find out. If it is too complicated to understand at the first time read the problem again and again.

Step 3
Look for clues words to show which operation to use,
Addition:
and…add…
addend…plus…
sum…more…
more than…
in all…total…
all together…
perimeter…
combined

Suctraction
Minuend…subtrahend
difference…subtract
minus…take away…
less than…remain…
are left…have left
how much more
fewer…are not…
decreased by…
how much change (money) is left

Multiplication
factor…product…times…of…
multiplied by…
area…volume…
each…twice=2x…thrice=3x… …how many times more…

Division
dividend…divisor
…quotient…
divided by…per…
half = ÷ 2…
separated…rate…
ratio…fraction…
decimal…part…
percent…

Beware…
Of red herrings! (false clues) In this case, numbers that are just there to trick you, but are not needed to solve the problem.

What to do
if you’ve read the question more than once, and you still don’t know which way to turn..

Then just do something!
You know there are four operations and you’ll have to do at least one of them. So pick one.
You know you need to do that operation using at least two numbers, so pick two of the numbers in the problem. Then either add ‘em, subtract ‘em, multiply ‘em, or divide ‘em. You may be wrong, but YOU MAY BE RIGHT!

Step 4
Solve the problem.

Step 5
Now think… Does this answer make sense? Would I expect this to be the answer?

Remember
If you ONLY answer half the question, EVEN if you get that half 100% right… That’s only 50% of the question… And 50% is an F!

Step 6
Ask yourself… Are there more parts to this question? (Some questions have two or more parts!) Check your work… just work backwards, using the opposite operations and see if you end up where you began.

Congratulations!
That’s how to solve a math problem.
Some more clues for math sleuths…
Always try something.
Never try nothing.
Show your work and hand it in. Even if you don’t make it the whole way, you may have come close.
