If x times 3 = 3x and you
subtract 12 = y over 3x squared, what are y and x? We will never know. Apparently it doesn't matter. Order of
operation matters. Order of operations is a way of thinking logically - so says
the mathematician. Do you know how
boring you sound? Only math nerds
understand the numbers game and the results of getting there - though most of
the problems are never completely finished - they are written down as far as
they can go. So an acceptable answer
could look like this: 4x+3q+8-7n=y^12 What?????
If we don't ever know what q or y or the rest of the letters are -
what's the point??? Roland says it's to
learn logic. I don't learn logic! I am too dang frustrated to be logical. I want to scream, swear, pull out my hair,
and hurt whoever it is that came up with x(3-6)+[6*(n-q)4]-12x in the first place. Give me a break! I was not put on this planet to answer mixed
up number/letter riddles. This is NOT my
lot in life. On top of that I'm I have
to have dictionary just to translate words such as "Polynomial" and "Monomial"
Is this a math class or an English class?
Make up your mind. Or maybe
"algebra" means "a combination of letters and numbers that will
either a) have a person so confused that they may end up hating all forms or
math or b) you will be able to relate to this subject better than people and
math will therefore become your best friend"
I don't know how many students are in my math class. I'm guessing thirty. It appears that there are a couple of math
nerds, but overall, the majority of us despise math, don't speak math, get lost
in math, are confused by math, are taking the course because it's required and
pray that we may pass the course just to get it over with, hate math, just
don't get it, don't really care. Guess
which group I fall into?
Recently my instructor posted the following: One of the big topics for this week was
simplifying a problem using the correct order of operations. Why is this so important? Take the following problem for example:
2(8=7)
- 3 x 4 + 2
Let's
say two students are working together to simplify this problem. Student A chooses to work the problem in the
following manner:
2(8 + 7) – 3 x 4 + 2
2(15) – 3 x 4 + 2 Parenthesis
first
30 – 12 + 2 Multiplying in
order from left to right second
20 Adding and subtracting in
order from left to right last
Student
A got a final answer of 20
Now
let's say Student B chooses to work the problem in the following manner:
2(8 + 7) – 3 x 4 + 2
2(15) – 3 x 4 + 2 Parenthesis first
30 – 3 x 4 + 2 Multiply starting at the left
27 x 4 + 2 Continue from left to right with
subtraction next
108 + 2 Continue from left to right with
multiplication next
110 Addition last
Student B got a final answer of 110.
Which student is correct?
This would be my answer:
Student A would be the correct answer because he/she is using the correct order of operations (PEMDAS) but I understand how Student B would come up with his/her answer - IT FEELS LOGICAL to do it that way.
Simplified? In math? Unless we are doing basic addition or subtraction, for me personally, the word "simple" can be associated with anything math related. It's an oxymoron.
I think algebra is an oxymoron.
