Den.... It is PEDMAS and not PEMDAS

Only an illiterate will equate the bolded

Is 3^4 = 3 of 4 ?
For your info 3^4 = 3x3x3x3 while
3 of 4 = 3x4

primus101:
Lol. I haven't checked yet.

Shym3xx:
Another id.iot post induced by illiteracy.

Americans don't use "Of", they use "Exponent" and that's how syllabus is. Ditto how the say "Parenthesis" for "Brackets".

And stop applying the logic of pure maths to applied maths, you m0ron.

Anyway, when you're given a maths question in the UK - use the junk you typed there and see if you won't fail woefully, effing clown.

You can go ahead and swim in your folly after seeing what is below:

From American dico:

ex·po·nent (ĕk′spō′nənt, ĭk-spō′nənt)

A number or symbol, placed above and to the right of the expression to which it applies, that indicates the number of times the expression is used as a factor. For example, the exponent 3 in 5^3 indicates 5 × 5 × 5; the exponent 2 in (a + b)2 indicates (a + b) × (a + b).

6-1x0+2÷2 = 7, using PEMDAS

6-1x0+2÷2 = 5, using BODMAS

I don't think PEMDAS and BODMAS are basically the same.

Has PEMDAS Really Taken Over From BODMAS?


"In those days", one of the rules of Algebra in solving of equations was to use the mnemonics BODMAS - as the order of operations to follow....

B - for Brackets
O - for Of
D - for Division
M - for Multiplication
A - for Addition
S - for Subtraction

Yesterday while discussing this "almighty" order of solving equations with a young undergraduate, he politely informed me that my BODMAS of yesteryears is no more! That rather it is now PEMDAS that is now being taught in schools and colleges.....

P - for Parentheses
E - for Exponent
M - for Multiplication
D - for Division
A - for Addition
S - for Subtraction

While an ancient like me can allow the fresh nomenclatures for "Brackets" and "Of" of yesteryears, when did "Division" lose its position for "Multiplication"? He could not answer me!

Finally, is it now true that "Multiplication" has taken precedence over "Division" against what the Entebbe Workshop that became "Modern Mathematics" of the 1960s taught to people of my generation?

sniperwolf:
The rule still remains BODMAS. Parentheses and brackets are used interchangeably.
Of, Division and Multiplication are both Commutative and Associative. Same can be said for Exponent, Division and Multiplication

gyroscopic:
can someone solve: 12÷6×2 using BODMAS and PEDMAS and prove to us they are same?

idros4real:
Wrong answer
= 6-0+1= 5 with PEDMAS
You have to add 0+1 before subtracting it from 6 and the answer will be 5.

Sexytemi:
what does that have to do with bodmas or pedmas??, abeg swerve oooo.... (catwalks away)..

femi4:
The parenthesis nko?

Sexytemi:
And whats that

Rhemmymatician:
Division is NOT commutative

This august wil be my junior year studying aeronautical engineering and I didnt find that shít funny...In a space of 2 years since I finished high school maths changed completely even now in elementary school, there's a new way of teaching maths called common core...look it up. My cousin was fuming that her son got an F on a simple maths problem for a 3rd grader she helped him with. When I saw it, I was confused for the first 1 and a half minute. But thats how humanity works...EVOLVING.

By the way, Parenthesis is what we call Brackets in the states...Its still the same sequence really.

Don't bother

SirBrightoc:
Dear,
Is Division commutative and associative?
COMMUTATIVITY: a ÷ b and b ÷ a are they equal?
ASSOCIATIVITY: a ÷ (b ÷c) and (a ÷ b) ÷ c are they equal?
CHECKS: 6 ÷ 2 = 3 while 2 ÷ 6 = 1/3. They are NOT equal.
12 ÷ (6 ÷ 2) = 12 ÷ 3 = 4, while (12 ÷ 6) ÷ 2 = 2 ÷ 2 = 1. Also, they are NOT equal.
DIVISION is neither associative nor commutative.

sniperwolf:
Division is neither commutative nor associative. But when you use OF, DIVISION and MULTIPLICATION, you get the same solution however you want to rearrange the problem and same can be done for EXPONENT, DIVISION and MULTIPLICATION
a ÷ b x c = a x c ÷ b
