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

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

16 + 16 +4 -16 = 20

4x4=16

16+4=20

20x4=80

80+4=84

84-4=80

80x4=320

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

= [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

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 :)

order of operations apply

( laws of math )

The people not getting it probley didn't make it past the 10th

4x4=(16) +

4x4=(28) +

4 = (32) -

4x4=(16) =

20

Maybe this will show you how it should be done.

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

Just shows how much one forgets of math classes taken a long, long time ago... But I had a sense that I was wrong immediately after I posted my original reply. ****, I used to be pretty good at this...:-)

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.
