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 />
16 + 16 +4-16<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
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.
Because they fail at math.
Obviously you failed math as well.
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
let me clarify for you, since you are such an idiot your brain capacity is lacking.
The equation is as follows. 4 x 4 + 4 x 4 + 4 - 4 x 4.
You are correct it's PEMDAS.
There is no P or E in this equation, so let's do the M next. Remember to not touch the addition yet. so you will multiply the 4x4 but leave the +4 and - 4 alone for now, so you get 4 x 4 = 16, then immediately after that is another 4x4, so that is 16 as well. We have a +4, so we ignore that, for now, then we have a 4x4 at the end, which is another 16.
The equation now looks like this: 16 + 16 + 4 - 16. NOW let's do the addition. 16 + 16 + 4 = 36. 36 - 16 = 20.
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
(4x4) + (4x4) + 4 - (4x4) = 20<br />
16 + 16 + 4 - 16 = 20<br />
We are told in school that you must do the multiplication in a problem first then do the addition and subtraction.
Because you're wrong it's 20 not 68.<br />
(4x4=16)+(4x4=16) = 32 +4 =36 - (4x4=16) =20
I got 48
Omg you failed to answer this.<br />
Put the parenthesis in the right place if you need them.<br />
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
(4x4) + (4x4)(+4-4)x4=128<br />
(16) + (16) + (0) x4=128
It's 20: 16 + 16 + 4 - 16
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
A scientific calc will answer 260 <br />
4x4x4x4+4+4-4 = 260<br />
A non scientific calc wil be 320
