The second is correct as according to "order of operations" one must do parentheses, thenexponents, multiplication or division as they appear left to right, and lastly addition or subtraction as they appear left to right. All calculators , to the best of my knowledge, have this preprogrammed into their "brain". To get the 1st answer, you would need to insert parentheses around the first "4 +4".4+4(4+4)
It seems ambiguous to me and searched that calculators have different answers with this. Either 64 or 36.
4+4(4+4)
8(4+4)
8(8)
64
4+4(8)
4+32
36
Thank you so much!
A substitution in x can give you a clarity ceck.4+4(4+4)
4+4(4+4)
8(4+4)
8(8)
64
4+4(8)
4+32
36
Thank you so much!
Many simple, so called 4-function, calculators don't know about order of operations. They work with a simple single-accumulator architecture that is only capable of working with the value in the accumulator as one operand and the newly entered value as the other operand storing the result back into the accumulator.The second is correct as according to "order of operations" one must do parentheses, thenexponents, multiplication or division as they appear left to right, and lastly addition or subtraction as they appear left to right.

Exactly right. The operations in the parentheses must be done first, then multiplication, and finally division.The second is correct as according to "order of operations" one must do parentheses, thenexponents, multiplication or division as they appear left to right, and lastly addition or subtraction as they appear left to right.

I learned it as "PLease Excuse My Dear Aunt Sally", for "Parentheses Exponents Multiplication Division Addition Subtraction"Actually I learned it as My Dear Aunt Sadie.
Odd, I was taught PEMDAS.Remember BIDMAS!!!
B - Brackets
I - Indicies (squared, cubed, etc)
D - division
M - multiplication
A - Addition
S - Subtraction
Same thing. PEMDAS is the American version, BIDMAS is the european version.Odd, I was taught PEMDAS.
Parentheses, Exponents, etc;
I think you mean "Please Excuse My Dear Aunt Sally" or PEMDAS.Actually I learned it as My Dear Aunt Sadie.
You do division BEFORE multiplication IF it appears to the left of the multiplication. Multiplication and division have the same "weight" so they are done left to right in order of appearance and the same with addition & subtraction.Exactly right. The operations in the parentheses must be done first, then multiplication, and finally division.
Oops, I guess I worded that wrong. Yes, that's what I was always taught--M/D (left to right), A/S (left to right). Thanks for specifying for meYou do division BEFORE multiplication IF it appears to the left of the multiplication. Multiplication and division have the same "weight" so they are done left to right in order of appearance and the same with addition & subtraction.
This is the first I have every heard of either.Same thing. PEMDAS is the American version, BIDMAS is the european version.
