Question

What is the value of :

\(72 \times 12 \div 6(5 + 1)\)

Answer 1

is this some kind of order of operations trick or something?

Answer 2

I am in doubt I want to clear that...

Answer 3

You will use PEMDAS here ??

Answer 4

yeah the parentheses first either way\[72\times12\div6\times6\]now the OO doesn't matter, but I'm not sure whether to consider it as\[72\times12\div(6\times6)\]

Answer 5

its just mathed from left to right since ther eis no trump on a / or *

Answer 6

You should do multiply first there @TuringTest

Answer 7

yeah, I'm inclined to agree with that^
just\[72\times12\div6\times6\]

Answer 8

it won't matter, you can do the parentheses last if you want

Answer 9

Yes what will you use here division or multiplication in priority ??

Answer 10

According to PEMDAS you should multiply first 72 with 12 right?? @TuringTest

Answer 11

u go with BODMAS rule
72*12/6*6
72*2*6
864

Answer 12

pemdas doesnt have a division multiplication priority ....

Answer 13

@Nick_Black I will come to BODMAS later..

Answer 14

So what will you do next @amistre64

Answer 15

i already stated that i would follow the protocol and work it left to right

Answer 16

1/3x is spose to be 1/3*x but laziness has us forgo the ()

Answer 17

So according to you @amistre64

864 \(\div\) 6 \(\times 6\) = 864 right ??

Answer 18

72*12 = a

a/6 = b

b*(6) = finale

Answer 19

Yes I did the same..

Answer 20

then yes :)

Answer 21

without a proper use of grouping symbols; thats the way i would read it -- cold turkey

Answer 22

I am in doubt because :

BODMAS gives priority to Division..

And PEMDAS gives to Division..

Still there is no difference in answers why how ??

Answer 23

Sorry PEMDAS to multiplication...

Answer 24

pedmas doesnt give any priority

Answer 25

We have to just go left to right ??

Answer 26

yes, in the absense of any groupings, we go left to right

Answer 27

Yeah we have to solve brackets first...

Answer 28

have to? no but its helpful

Answer 29

For our Convenience...

Answer 30

i like to format it as:

1) groupings
2) dm or md
3) +- or -+

as prioritites

Answer 31

Okay I understand that..

Answer 32

More suggestion will be appreciated..

Answer 33

Thank you @Nick_Black
Your medal is remaining..

I will remember it..

Answer 34

we should take its derivative while we have it on the table :)

Answer 35

Can you @amistre64 give him a medal??

Answer 36

What ??? @amistre64

Answer 37

i can, aaaannnndddd my medals are worth more to the smartscore .... if that matters

Answer 38

Yes I can understand your point in that..

Answer 39

thanks to u i knew about PEMDAS today

Answer 40

That is why I posted it...

Answer 41

Because I am also from India..

Answer 42

@amistre64 I have one more doubt if you can clear that..

Answer 43

i can try, but i tend to give more doubts than i clear up lol

Answer 44

What is FOIL..??

I have heard everyone saying that.

Answer 45

FOIL is a memory aid to those who have lost the ability to multiply

Answer 46

Is it having any full form ??

Answer 47

In case of distribution it is used I guess..

Answer 48

take 2 binomial expressions (a+b) and (c+d)

to multiply them we simply

a+b
c+d
------
ac + bc
ad + bd
--------------
ac + bc + ad + bd

FOIL is used to express the exact same thing, but thru theu use of memory aids to get you to multiply the parts togther in a specific order:

Firsts, Outers, Innards, Lasts

Answer 49

since the memory aid is only useful to binomials; i feel its rather useless overall ...

Answer 50

Okay thank you so much, I understood now @amistre64

Answer 51

youre welcome; the aggravation occurs when people ask then; how do i foil these? towit the memory aid becomes useless clutter :/

Answer 52

Ha ha ha...
