I Need Help Solving This Math Problem

[jack3]

Ask Biden.

 

[Slade3200]

I understand what you're saying perfectly now but that's I'm pretty sure that's not what PEMDAS is as nothing says that we're only limited to the existing numbers in the equation without adding to them. I'm not sure where you're getting that part from as it's not a word problem.

Math is simply a numerical expression of things that happen in real life. The situation where I added and subtract apples from the table is reflected in a mathematical formula. Formulas should also be able to be explained in real life scenarios. It helps understand what’s happening.

You shouldn’t just simply follow formulas if you can help it. Try to understand why the formulas exist and how they are being applied.

Yes but with all due respect towards you you can't just go changing the original formula either.

Jesus, it will be 11. PEMDAS is an axiom. Don't ask why this (if you don't want to be a guru), just follow the rule.

 

[MisterBeale]

It's alright, he doesn't bother me one bit. I just have a little trick that I live by. If somebody is making fun of you, just laugh at yourself first and beat them to the punchline. Then what fun is it to make fun of you anymore.

I don't think that MisterBeale was laughing at me to be mean about it though, I think that he was just simply making a funny joke. Or at least that's how I took it as I'm not overly sensitive about these things.

Bingo.

None of us is perfect.

We all have our strengths and weaknesses. Some our good at social things, others intellectual pursuits.

It is no big deal to not be the smartest person in the world at this or that. . . but to be able to laugh at yourself, and not take things too seriously?

That shows character. Good on ya.



You won this round girl.

Thanks but isn't it none of us are perfect? Sorry, I just wanted to be a smartass.

 

[MisterBeale]

Those 5th Graders on that show would Crush the OP in any trivia question, math question and overall general knowledge.

OP is laughing at being laughed at and doesn’t even know it.

Nope.

The folks on here that are able to roll with self-deprecating humor, are the kindest we have. They don't need to prove anything to anyone in my book.

 

[Slade3200]

Yes but with all due respect towards you you can't just go changing the original formula either.

I’m not changing the original formula. I’m just explaining how it works. You do Parenthesis and Exponents the Mult/Division from left to right..: then Add/subtract from left to right. That’s how the PEMDAS works. The letters are just a trick to remember order of operations but you have to understand how to apply it.

Easiest way to approach an equation is to bracket the multiplication and division and the sum from left to right.

For example:
3x3-3÷3+3
(3x3)-(3÷3)+3
9-1+3=11

You can break down any equation like that
3x4-10÷2+6
(3x4)-(10÷2)+6
12-5+6=13

Here you try one:
2x4-6÷2+5

Right you are.

Migraine this morning.

I just got up from a 14 hour sleep, haven't had my coffee yet, and did not proof read.

I'm lazy. I seldom proof read before I hit post.


The thing is, in my head, while I compose, I talk talk many different vernaculars by many folks in segments of society that I have lived.

In some segments of society, they would use is rather than are, I shit you not. I've lived in them all, and so I often code-switch in my mind, especially if I had been recently out doing commerce or interacting with various parts of society.


Nothing worse, IMO, than a grammar NAZI

I have seen these problems worked both ways--logically as a basic math people do it to get 5 as an answer and using the advanced math formulas those use to get the 11 answer. Which is right? I don't know as my brain doesn't work very well in advanced math.

I used to post these kinds of things in the Coffee Shop but the math people never came to the same conclusion as us basic math people:

I'm sorry but I don't have a clue what formula you're using as everything I've read about PEMDAS it never changes no matter what direction you're going in. Oh and I don't mean anything personal btw but I simply can't follow you.

Right you are.

Sorry, I just thought that it could be an awesome teachable moment that even you make mistakes. No biggie.

Here maybe it will help if you refer to this website. Note the left to Right element.

PEMDAS Meaning

Many people use the acronym PEMDAS to help remember the order of operations. PEMDAS stands for “Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.” The acronym also helps to remember that we start simplifying the expression from left to right, just like we read “PEMDAS” from left to right.

The final set of operations “AS” – addition and subtraction. Just like multiplication and division, addition and subtraction are a set of inverse operations, so we treat them the same by using whichever operation comes first from left to right.

The order of mathematical operations is parenthesis, exponents, multiplication, division, addition, and subtraction. Learn all about the PEMDAS process here!

3x3-3÷3+3

Ok, I'll try.
Give it a read.

3X3-3÷3+3 as written has no ( ) nor exponents. Therefore from Left to Right, you M or D, before you A or S.
3X3-3÷3+3
9 - 1 + 3
Now you only have A or S, and you do it from Left to Right.
8 + 3

11.

Now Slade3200 is being very patient and is explaining it very well.

If you change 3X3-3÷3+3 to (3X3)-(3÷3)+3 it doesn't change the answer or the order of PEMDAS because the ( ) were put around the operations ( add, subtract, multiply, divide) that you were doing first to begin with. So, adding ( ) to these spots changes nothing.

Now, if you put the ( ) around different parts, it will change the order and therefore change the answer. Let's write it this way.
3 X (3-3)÷(3+3). parentheses first.
3 X 0 ÷ 6 Now only M and D exist, and you do those from Left to Right.
0 ÷ 6
0

 

[Foxfyre]

0
250+250+250+250=1,000
0+250+250=500
250+0+250=500
250+250-250x0=0

That's what I got too but others say no, the parentheses apply and such.

And my brain just doesn't work any more complicated than the simplest formula. And it isn't important enough to me to retrain my brain to think in advanced math until I need it. And so far I haven't.

250+250+250+250=1,000
0 + 250 + 250 = 500
2(125) + 0 + 250 = 500 2 Bananas means 125 each banana
250 + 125 - 250 X 0 = 375 250 X 0 = 0 is done first. Leaving 250+125-0 = 375

 

[The Duke]

Here you try one:
2x4-6÷2+5

Now THAT's 3!

Oops, or 8.

I think he's wrong on the last one as you do multiply first.

You might be wrong here?
250+250-250x0=0

250+250-(250x0) =500 with multiply first.

 

[Road Runner]

Now THAT's 3!

Oops, or 8.

No you were right the first time. It's 3.

I think he's wrong on the last one as you do multiply first.

You ALWAYS do as that part doesn't change.
