Please sir I really need your help as I am struggling with Pemdas. What does the d and the s stand for. Thank you

[@enriqueiii9209]

P = ( )
E = ² POWER, EXPONENT
M = x
D = ÷
A= +
S = -

Keep in mind that Pemdas comes after operand interpretation.
For example an obelus can be used for subtraction, grouping, and was initially used as you would use ratios. When used as a ratio what comes before it Pemdas applies, what comes after Pemdas also applies, but as a ratio the obelus sits outside of PEMDAS.
ISO 80000-2 states for division you should not use the obelus, you should use a Solidus. For ratios you should use a colon.

Parentheses - that's any form of bracket, including ( ) [ ] { }
Exponents - that's powers and roots
Multiply and Divide - both have equal priority and are performed left to right
Add and Subtract - both have equal priority and are performed left to right
However, this doesn't tell the full story. For example, the rule is silent when it comes to factorials (like 6!) and functions (like sin x), and a square root sign can have a long tail over an expression, making it a combination bracket plus exponent.

Surely, you know Google is your friend! Instead of struggling you could simply have entered the same question there and quickly got the answer.

He verbally adds pauses in the first expression which do not match what is written and then verbally reverses himself in the second expression.

I m not getting the right answer to that last problem with a number one factorial. n(n-I), etc. I substitute “1” in that factorial equation and I get zero….1(1-1)= 1(0)=0, so the answer I get in the problem was “-15” and not”-14.” Where am I wrong?!

[@LarsV62]

Never include zero when doing factorial calculations. Only go from the given number down to 1 (or, if you prefer, from 1 up to the given number).

[@harrymatabal8448]

But sir wtf do you use fucktorial 4 instead of 24.

[@lynnballantine5686]

@@harrymatabal8448 4 factorial is equal to 24. I;m not sure what you are asking here but it seems you just wanted to use this vulgarity to prove how clever you are. Not clever so much as immature.

[@grahamshakeshaft2373]

@@LarsV62 Indeed, if you did include 0 in factorials then zero would be the answer to ALL factorials!

[@Astrobrant2]

Having 1! is kind of pointless unless there's a parenthesis in front of it.
You should have had one more example which included an exponent.

[@timgerk3262]

This is actually counter-productive. You're planting incorrect memories thar make learning harder. Demonstrate only the correct method, unless you're one on one tutoring and need to point out a prior error.

[@alexandrabloch1687]

Sorry

This is complette and utterly unnecessary nonsense. Any self respecting mathematician will use parentheses to get rid of any possible ambiguitties.

[@BernardGreenberg]

Completely and utterly correct.

[@paulfrank8738]

Sure, It's a crappy way to write an equation under normal circumstances. However, I think it's a completely valid equation to teach or test an understanding of the finer points of PEMDAS. Most examples and problems in a Math text book are contrived. This is also a contrived example that was clearly created for the purposes of education.

[@BernardGreenberg]

@@paulfrank8738 No, "PEMDAS" is a tormula for allowing people to be sloppy, hand an expression to someone else who misinterprets it, and then thumb your nose at them and say :"I was RIGHT!". It stands for "Pity Any Mathematician (who) Does Anything Similar", doesn't it. "Fine points of interpreting a written expression" translates to "structure or vehicle failed because of a misunderstanding between engineers". There should not be "fine points of understanding the meaning of an expression." Teach the forest, not trees.

[@paulfrank8738]

@@BernardGreenberg So you're saying it was a conspiracy by the mathematicians who came up with it, and those who adopted it, and those who kept using it for the past 60+ years? They did it to be able to thumb their noses at non-mathematicians? Seems legit.
By the way, you wouldn't happen to also believe the Earth is flat would you?

[@BernardGreenberg]

@@paulfrank8738 Mathematicians didn't come up with it; teachers did. Mathematicians, scientists, and engineers know better than to use expressions subject to misinterpretation. I stand by what the head of the thread guy said, that any self-respecting mathematician would not write such a foolish expression.
I can say "brothers and sisters I have none, but that man's father is my father's son!" or I can say "that man is my son", which is the meaning of the former stupid riddle. Writing expressions as riddles is similar.
The one in this page isn't all that bad; but ones with a foolish "divided sign" (not /) are all over RUclips. Mathematicians, engineers, and scientists use parentheses. Computer languages have their own indvidual and different rules, but that's a different world. "Operator priority" is a reasonable concept to teach (not "pemdas"). CLARITY is a better concept to teach,
