320, none of the operations are in brackets, so sequence prevales:

4x4 (=16) +4 (=20) x4 (=80) +4 (=84) -4 (=80) x4 = 320

Sorry you are incorrect PEMAS prevails for the correct answer of 20'Bedmas as stated below is also correct. PEDMAS  and BEDMAS are the same.  There are a couple of things to remember when applying the PEDMAS/BEDMAS order of operations. Brackets/Parenthesis always come first and exponents come second. When working with multiplication and division, you do whichever comes first as you work from left to right. If multiplication comes first, do it before dividing. The same holds true for addition and subtraction, when the subraction comes first, subtract before you add. It may help to look at BEDMAS like this:B - Brackets or Parenthesis

Sequence does not prevail...  BEDMAS is the only answer, thus the outsome is 20.  Brackets are not required, the laws of math dictate the method for solving the equation.

ACTUALLY... it is PEDMAS
BEDMAS...There are no bracets, and BEDMAS and PEMDAS are he same except for the Parentheses and Bracets.
4x4+4x4+4-4x4

 

(4x4) + (4x4) + 4 - (4x4)=20

16 + 16 + 4 - 16 =

(32 + 4) - 16 =

36 - 16 = 20

The answer is 20. Please excuse my dear aunt Sally. Parenthesis exponents multiply decide addition subtraction is the order u have to solve these problems and that little saying is an easy way to remember lol
answered Sep 9, 2012 by anonymous
Bedmas would apply, if there were Brackets in the equation - as there isn't, your response is irrelevant.

16+16-16+4=20

The answer......simple!
answered Sep 9, 2012 by anonymous
20. Based on order of operation you would multiply first, then add or subtract.

 

(4x4)+(4x4)+4-(4x4)

16 + 16 +4 -16 = 20
answered Sep 9, 2012 by anonymous
BEDMAS applied the answer is still 320 becasue nothing is bracketed, so the order would be solved as written.

4x4=16

16+4=20

20x4=80

80+4=84

84-4=80

80x4=320

The answer is 20. Absent any brackets, the order of operations is still used, and multiplication is done before addition/subtraction.

Laws of Maths dictate that multiply and divide take precedence over add and subtract. The answer is 20.

Order of operations prevails unless dealing with parentheses - therefore, the answer is 20.

The answer is 260
answered Sep 15, 2012 by anonymous

the answer is 20. BEDMAS is just a way of remembering the order of operations. It always applies. If there are no brackets, look for exponents, if there are no exponents, then look for divisions, if there are no divisions, then look for multiplications, if there are no multiplications, then do additions, lastly you would do subatractions, if any.

so in this case it is as follows:

4 x 4 = 16 + 4 x 4 = 16 + 4 - 4x4=16 (multiplication always comes before addition or subtraction), then 16 + 16 = 32 + 4 = 36 - 16 = 20 (additions are always done following any multiplications and subtractions are always done following and additions). Order of operations never changes, despite what or what is not in the equation.

The state of education in the world today is scary, i wonder what the requirements are to pass mathematics in this day and age considering the number of people poorly skilled in math. I'm not even talking algebra or trigonometry which can be difficult to master. I'm just talking basic math. Stuff people learn in like grade five. It's getting very scary.

............
= 4 X 4 + 4 X 4 + 4 - 4 X 4

= [4(4+4)] x [4(4+4-4)]

=(16+16) x (16+16-16)

= 32 x 16

= 512

OR

= 4 X 4 + 4 X 4 + 4 - 4 X 4

= 16 [ (4+4) (4+4-4) ]

= 16 (8 X 4)

= 16 X 32

= 512
answered Sep 16, 2012 by anonymous
No, that's wrong. You didn't follow the order of operations!

4 x 4 + 4 x 4 + 4 - 4 x 4 = becomes,
16 + 16 + 4 - 16 = becomes,
36 - 16 = 20

This is very basic math. Order of operations always apply, the lack of brackets only means that you simply move on to the next operation in the order e then d then m than a and finally s :)
Why do people who obviously do not know answer these questions? It's 20. If you are too dumb to figure that out, don't comment on answers.
answered Sep 16, 2012 by anonymous
Maybe you should try not to be such an *** and yes I got 20. Instead of being an *** why not try and educate the ones who got it incorrect
16x+4 because "x" is a variable, and ×,•,*,and variables next to numbers or other variables are operators for multiplication. (X×x) Position is critical in mathematics.

This is the Algebra 2 question; 4x4+4x4+4-4x4=(16x+4) Not the Pre-Algebra question 4×4+4×4+4-4×4=(20) Or a Grade School series of questions; "Class What's 4×4=(16), 16+4=20, 20×4=(80), 80+4=(84), 84-4=(80), 80×4=(320)" This is how math teachers determine who is cheating, hopelessly behind, has disorganized processing, and who has been paying attention or is gifted. 4x4+4x4+4-4x4=16x+4

20

Maybe this will show you how it should be done.

It does not matter if operations are in brackets or not.

answered Sep 17, 2012 by anonymous
Huh? Is your comment a typo??? From what you put in parenthesis the answer would be incorrect at 32. 16+28+4=48-16=32. I think you meant that 28 to be 16. If that is what you meant then yes you get the correct answer of 20; 16+16+4-16=20. I think you must have a typo here
(4x4)+(4x4)+4-(4x4)

Since so many people insist x is an operator of multiplication and not a varible (even though this is an Algebra 2 question). My final answer is: 4x4+4x4+4-4x4= No Brackets, No Exponents, Process Multiplication 16x1+16x1+4-16x1= Oh no, what evil have I done. "x" can still be an operator or a variable. Hey, look we have a ±16x1, those cancel out without any BEMDAS conflicts. 16x1+4= Now we have a conflict either you ***** all thought that this is an Algebra equation and process 16*1+4=20, or accept that x is a varible get rid of the ridiculous "•1" to get 16x+4= and x=[(ans)-4]/16 Since we've managed to prove that Math is now a religion and answers can be anything you please (1+2=4, 4×4=12), I leave you with the proof of all thee that trust in [()], ×,÷,+,-; 4x4+4x4+4-4x4=16x1+4. Go forth and *. Amen

Thanks all for your replies, I see now that I was wrong, and that the answer is  indeed 20, and not 320.

I think 100% people failed to answer this but me :)
The ANSWER is 8!!
=4x4+4x4+4-4x4
=4(1X1+1X1+1-1X1)
=4(1+1+1-1)
=4(2)
=8
OR
=4(1X1+1X1+1-1X1)
=4(1+1X1+1-1X1)
=4(2X1+1-1X1)
=4(2+1-1X1)
=4(3-1X1)
=4(2X1)
=4(2)
=8
Apply the 1st method we have found 20 and 2nd method we have found 320. But how I calculate, that method both way the figure is 8.

PEMDAS always  applies whether parenthesis are written into the equation given to you or not.  If they are not, it is an understood rule that PEMDAS is always being used to obtain the correct answer.
