solve, this math question?

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

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

by
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.
by
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
by
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
by
Actually you're using PEMDAS incorrectly. It's 320. Just look at the second answer from the top.
Bedmas would apply, if there were Brackets in the equation - as there isn't, your response is irrelevant.
by
16+16-16+4=20

by
20. Based on order of operation you would multiply first, then add or subtract.

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

16 + 16 +4 -16 = 20
by
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
by
WRONG, WRONG, WRONG! "Order as written" has nothing to do with it. ALWAYS, ALWAYS perform ALL multiplication and division BEFORE performing any addition or subtraction. The answer is 20!
PEMDAS

16 +16 +4-16=

36-16=

20

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

Even though there are no brackets, all multiplications must be performed before the addions or subtraction are performed. The answer is 20.

The answer is not 320. It's 20. Look at website I posted. Even though this isn't an equation, rules of operations still apply.

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 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

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.
by
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.

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 fudge 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.

I am amazed by the sheer variety of wrong answers posted here. I don't know if you are the same "anonymous" or if there are multiple people identified as "anonymous," but your wrong answers just keep piling up.

Just because there are no parenthesises does not mean the remaining order of operations is ignored.  The multiplication would still need to be calculated first (even in arithmetic).  Then you would perform the addition and subtraction.  Where it becomes interesting is which direction you lead from.

From left-to-right, the answer is 20.

16+16=32

32+4=36

36-16=20

From right-to-left, the answer is 44.

16-4=12

12+16=28

28+16=44

The general convention is to solve the problem from left-to-right.  However, there are some programming languages that solve from right-to-left.  That is why you should always make your equations as unambiguous as possible.

Its not algebra or even basic algebra as there is no parenthesis neither are we asked to assume parenthesis. It is basic arithmetic which is even easier than the basic algebra. The answer is 320. If you can't handle that and insist on trying to make it into an algebraic equation then have your 20.

It doesn't matter what tricky little methods you'd like to employ to think you're smarter than everyone else and prove everyone wrong. The reality of the matter is that it's a simple equation, and according to the laws of mathematics, it is solved by following the order of operations or PEDMAS. There are many correct examples listed below that plainly and irrefutably demonstrate that the answer is 20.
by
by
For X to be a variable and used as a algebra equation, you must have an eqivalent after the plus sign.  Since their is no equal there is no equation and therefore you must process as simple math using x as multiplication.  Put this into excel spreadsheet formula and got 20 as the answer.
by
The answer is 20 and let me tell you why. PEMDAS is the reason for this, you must multiply and divide first before you add and subtract, people that don't do this usually get the answer 320, which is incorrect, you must follow what called the "Order of Operations". Some will excuse it because there are no brackets, but I tell you that's wrong, because of the order of operations. (4x4)+(4x4)+4-(4x4) is the same as 4x4+4x4+4-4x4. Now if you did 4x2-1+5 your answer would be different if the problem was 4(2-1)+5, for the first one is 10 and the second one is 9.
by
before all the 20 answer people shoot me down,if we are multiplying 1st then why are we not starting with 4x(4+4) with an end result of 240? why does it have to be 4x4 from the start? i'm led to believe that excel is known to be wrong on matters like this,

There are no brackets or parenthesies.

Go left to right- do all multiplaction.

4x4+4x4+4-4x4

4x4=16

16+16+4-16

Now a +16 and a -16 can zero eachother out. leaving one +16 and a +4

16+4=20

But if you must see all the work-Just do the remaining parts from left to right

16+16+4-16=

16+16=32

32+4= 36

36-16= 20 (again)

you do your multiplying first then addition then subtraction  cause its a order of operations equation and you get 260

if u were to throw parenthese in the problem u would come up with different answers.

for example this:

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

16+16+4-16=

32+4-16=

36-16=20

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

16+16+4-4x4=

32+4-4x4=

36-4x4=

32x4=128

Anyone can throw in parenthese wherever. If the problem doesnt have them to show you what to do first, then you do the problem as is. It's a number sentence not order of operations.

Answer should be 20.  Even though there are no brackets, one needs to keep the 'Order of Operations' in mind.  So first, you multiply as indicated, then divide as indicated, add as indicated and then finally subtract.

This gibberish then becomes 16 + 16 + 4 - 16 which yields 20.  Ho hum.

In this problem there are three operations. x, +, and -. You do all the multiplication first. Then the addition. Then the subtraction. See above. PEMDAS (Please Excuse My Dear Aunt Sally is used to remember Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction.

Its a simple order of operations question. First do any parentheses and exponents (but there aren't any of thise so we need to skip to the next step), then do any multiplication or division from left to right (this is where we would multiply the 3 pairs of 4's), and finally add and subtract from left to right. So now we have 16+16+4-16 (because we multiplied first), now we can add 16 to 16 (32+4-16) add 4 (36-16) and finally subtract the final 16 to get 20.
