I Need Help Solving This Math Problem

[Harry Dresden]

Umm what does this thread have to do with Trump? Anyways my fiancee actually came up with five by solving the problem like this. So I now think that 11 is the wrong answer and that it actually is 5. As he seems to know what he's talking about.


3x3=9

3÷3= 1
1+3= 4

9-4= 5

chatGPT says its 11....

It’s was just a MAGA joke

Oh okay lol.

chatGPT says its 11....

Yeah well you can't always trust the internet and btw he also said that you don't add the parentheses. I actually believe that he has this one since he's a math whiz.

That’s not how PEDMAS is applied… multiplication and division first go from left to right and then the same is done with addition and subtraction…
your formula has the subtraction before the addition so it goes 9-1=8+3=11

3x3-3÷3+3
(3x3)-(3÷3)+3
9-1+3
Another way to look at it… if I put 9 apples on the table then take 1 away then add 3 we end up with 11 apples on the table.

Hold on running this by him for comment. As it would make things a whole lot easier if he was a member here. XD

Umm Slade3200 you do realize that you spelled PEMDAS wrong right?

 

[Slade3200]

Ha, yes you’re right. My bad. But if you want to be technical about it could look any of the following ways:
PEMDAS
PEDMAS
PEMDSA
PEDMSA

It really should like like
PE(MD)(AS) as the multiplication and division are done in order of appearance from left to right in the equation then the same with the addition and subtraction

Umm I don't think so. I'm pretty sure that it's just PEMDAS and that they're always done in the parentheses, exponents, multiplication, division, addition, and subtraction order.

That's correct.
Good answer.



I explain it through division and multiplication.

6° implies division by the same number, which equals 1.

7/7 = 1
11/11 = 1
x/x = 1

Why does 6° imply division by the same number, because of exponent rules.

6^4 divided by 6^4 = 6° , because 4-4 = 0, which equals 1.

Patient Zero

Or, going from the other direction, ask what does 1 equal. It equals the same number divided by itself. Since the solution of exponent problems is to subtract the denominator from the numerator, the power would then be zero.

It’s not… I’ll show you why.

Let’s take a real life scenario.

I put 5 apples on the table. And then I take them off the table. And then I put them back on the table. How many apples are on the table? 5 right??
The formula for this is:
5-5+5=5
Right?

Now if we applied the PEMDAS the why your suggesting, the solve for that formula would be:
5+5=10
5-10=-5
Suggesting that there are negative 5 apples.

We know that isn’t the case because all I did was add the apples, take them off the table and then put them back.

So that shows that the order from left to right in the equation takes priority over the AS part of PEMDAS

Does that make sense?

No because I think that it would be 5+5=10-5=5.

No because I think that it would be 5+5=10-5=5.

Why are you moving the 10 in front of the 5 in the equation? If you did that with the way your man solved the OP it would look like.

9-1+3
4-9=-5

5-5+5
10-5=5
See why that doesn’t work?

There was never 10 apples on the table

Nope!! I just asked my fiancee and I was correct. You take the total of 5+5 and minus the other five in the equation. Still waiting on an answer of why.

Sorry but he is wrong… read my scenario again where I put the apples on the table, took them off and then added them back on the table. There was never 10 apples on the table. If your formula says there was then it is wrong.

You can always check by using a calculator

Your formula would look like this
5+5-5
Mine is
5-5+5

Let’s do it with 3,2,1
I put three apples on the table. Take two away. Eat one and then put the other back o the table. There are 2 apples left on the table. Right?

The formula is
3-2+1=2

If you did it your way you’d get:
2+1=3
3-3=0 no apples on the table

That method is wrong because we know there are two apples on the table. Get it?

Looks legit, waiting on an explanation from him of why he did it that way.

Slade3200, where are you getting that there are only five apples from?

The original situation I laid out was I put five apples on the table, then I took five off and then I put five back on. It might be easier to look at the latest one where the numbers aren’t all the same. So I put three apples on the table I take two off and then I put one back on. There’s two apples on the table. The formula needs to go in the order that I put the apples on and took them off not doing all the addition first and then subtraction

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.
