Order of Operations (unless told not to use them) YOU ALWAYS USE THEM! PEMDAS, for those that forgot "Please Excuse My Dear Aunt Sally," Parentheses, Exponents (and roots), Multiplication/Division, Addition/Subtraction. In order from left to right do all parentheses, THEN all exponents/roots, THEN multiply/divide, THEN add/subtract -.-<br />

4x4+4x4+4-4x4<br />

16 + 16 +4-16<br />

32+4-16<br />

36-16<br />

20<br />

Not all calcs do order of operations for you, so if the calc "gives the wrong answer," YOU PUT IT IN WRONG

This is the right answer

there is a math and there is a calculator... :S<br />

if u are lazy and stupid u will use a calculator and u can get whatevah answer u want; if u want true u should know something about Order of Operations - BODMAS...<br />

and FYI correct answer is 20

no parenthesis or brackets then MDAS applies as a rule of mathematice,,,the correct answer is 260

You state PEMDAS and then you still get it wrong.

If you use a calculator the way it is 4x4+4x4+4-4x4 it comes up 320. If you bracket it off yes comes up 20.

neither

(4x4)+(4x4)+4-(4x4)<br />

16+16+4-16<br />

20.<br />

Because they fail at math.

Obviously you failed math as well.

4×4+4×4+4-4×4=?

P.E.M.D.A.S.

4×4=16

16×4=64

64×4=256

256+4=260

260-4=256

256+4=260

IF you do the order of of operations correctly, this is the answer you should get. The order of operations from above is please excuse my dear Aunt Sally. Parentheses, exponents, multiplication, Division, addition, subtraction. Considering there is no parentheses exponents then you do the next which is, multiplication. Then you do all the adding and subtracting

you are ******* retarded

i do not like this

I can't just decide how to pronounce a Russian word, for example. I have to follow the rules of that language. It's the same with Maths. You have to follow the rules of reading mathematics, which is brackets, then powers, then multiplication or division left to right, then finally addition or subtraction left to right. Some people remember this with a PEMDAS or BOMDAS acronym. So for this question:<br />

No brackets.<br />

No powers.<br />

Do all the multiplication parts: 16+16+4-16<br />

Now add and subtract left to right: 32+4-16=36-16=20

You are correct that it equals 20, but there ARE exponents (or, "powers"). Any number multiplied times itself is, by definition, an exponent.

320

(4x4) + (4x4) + 4 - (4x4) = 20<br />

16 + 16 + 4 - 16 = 20<br />

<br />

We are told in school that you must do the multiplication in a problem first then do the addition and subtraction.

20

Because you're wrong it's 20 not 68.<br />

<br />

(4x4=16)+(4x4=16) = 32 +4 =36 - (4x4=16) =20

4*4=16,16+4=20,20*4=80,80+4=84,<br />

84-4=80,80*4=320

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

20

I got 48

29

Omg you failed to answer this.<br />

4x4+4x4+4-4x4=20<br />

Put the parenthesis in the right place if you need them.<br />

(4x4)+(4x4)+4-(4x4)=<br />

(16)+(16)+4-(16)=<br />

36-16=20

order of operations....answer is 20, you can try it many different ways and you will end up with a different answer....but order of operations is the way to go! PRMDAS

No... you can try it many different ways and if you are doing it correctly the answer will always be 20. And there are MANY different ways to solve this problem.

(4x4) + (4x4)(+4-4)x4=128<br />

(16) + (16) + (0) x4=128

So wrong!!!!

It's 20: 16 + 16 + 4 - 16
