And what do you do with the number inside the when you want to get rid of it?
You literally must distribute the coefficient before you can do anything with what is inside to remove Brackets, as per The Distributive Law, a(b+c)=(ab+ac), now you can work on getting rid of what is inside.
No, it’s written poorly to drive engagement. People read left to right and try to do math that way too, but if you want to be mean to people who don’t remember things they learned in elementary school then never applied in real life you write it like OP.
(8-5)5+2
Far easier for most people, but then you don’t get the arguments…
The engagement comes from people not remembering the rules of Maths
(8-5)5
That’s an invalid syntax. it’s 5(8-5) or 5x(8-5), nothing else. Why is it invalid? Imagine (8-5)-5 - am I multiplying what’s in the brackets by -5 (which gives -15), or subtracting 5 after doing the brackets (which gives -2)? Invalid syntax
Far easier for most people
Nope, it’s wrong for everyone, due to being an invalid syntax.
It’s written the same way literally thousands of math problems in thousands of textbooks have written the same type of math problem for the last 100 years. OP did not write it that way to be “mean.” He wrote it that way because it’s a legit way to write it.
The operational order is fucked, the way I rewrote is more readable, even if you remember the order. The only reason you’d write the equation like that is to be mean, there’s no reason to write it like that unless you’re trying to trip people up.
You got it wrong on your first try, didn’t you?
Lol, it’s not “mean” to write a math problem. The whole point of memorizing the order of operations is so that you can solve it no matter what order the equation is written in. No one wrote this problem on purpose just to make you fail to understand it, that’s dumb.
I fucking suck at math and totally just re-proved it to myself with this problem lmao.
It didn’t make sense to me to multiply the 3 & the 5 with zero consideration for the “2”. I have ALWAYS struggled with the steps to solve these types of equations.
So the answer I got was 21. Some of us are just bad with numbers, I s’pose.
The numbers in the equation and their totals are completely irrelevant to the order you perform the operations.
I don’t think it’s an issue of “being bad with numbers”, I think the issue is not understanding the logic or being able to understand the bottom up type of thinking or something.
This is absolutely not a problem of being bad with numbers. That’s like if I had trouble reading a Chinese sentence about gardening and said I’m just bad with plants. My issue is that I’m not familiar with the notation used to explain the concept - not a problem with the concept itself that the notation merely arbitrarily symbolizes.
Being good or bad at math is not really an inherent thing, aside from some geniuses and some people with disabilities. If you want to be good at math, you can be!
Its order of operations, to get rid of brackets do the internal, then the 5 tells you there was 5 sets of the amount in brackets. Rather than 2+5 first.
Pemdas, parenthesis first, for a total of 3. Then multiplication, 15, then addition. 17. What’s hard about this?
Nope, a total of 15.
There isn’t any Multiplication, only Addition and Brackets (and Subtraction inside Brackets).
And what do you do with the number inside the when you want to get rid of it?
You literally must distribute the coefficient before you can do anything with what is inside to remove Brackets, as per The Distributive Law, a(b+c)=(ab+ac), now you can work on getting rid of what is inside.
And what do you do with and and the b and then the a and the c? If you want to simplify the equation?
Add them, obviously 🙄
Guess I’ve been trolled.
BTW, there’s no “the a and the b” and “the a and the c”, there’s ab and ac, which need to be added. If a=2, b=3, and c=4, we have 2(3+4)=(6+8)=14
you go the other direction below the equator
Legit gave me pause for like half a second. Damnit lol
Isn’t the southern hemisphere above the equator if you live there
depends if you are normal or planar in ENU coordinates
What’s hard about it is people are fucking stupid.

I studied physics a bit and order of operations was always clear. Not sure why people are down voting this.

No it isn’t.
Wrong.
Because it’s written like that in Maths textbooks
Obeying the rules of Maths, as found in Maths textbooks

This was literally written for twitter content…
I just fail to see how you come to the conclusion that it was written in a “mean” way. It’s math, there is no “nice” way to write an equation.
it’s mean in that they intentionally wrote it to trip people up so we’d have this very conversion…
Yes, thank you! Sure, it’d be great if people remembered arithmetic rules, but just write it better and it won’t matter.
It’s written like that in Maths textbooks. i.e. there’s nothing wrong with it.
Some other parent’s thesis.
Cruel Parent’s Thesis?

That’s what the order of operations rules say to do. 2 doesn’t come into it until you get down to the Addition step.

If you don’t remember pemdas, you can use the longer P.lease E.xcuse M.y D.ear A.unt S.ally.
That’s the answer I arrived at as well, don’t feel so bad. I’m more of a writer than a calculator, though.
