@IrishBoy123 sorry if I was confusing I really don't explain things very well soooo

- freckles

I'm sorry what is going on in that problem?
are you saying:
\[4^{2-2(3x^5+1)}\]

- freckles

oh is that one x a multiplication sign

- freckles

\[4^2-2(3 \times 5+1)\]
after thinking about it
I think you mean this

- freckles

order of operations say to perform what is in the grouping symbols first

- freckles

in the grouping symbols you have 3(5)+1

- freckles

you have multiplication and addition there
the multiplication comes first then the addition

- freckles

so 3(5)+1=?

- anonymous

\[4^{2}-2(3x5+1)\]

- freckles

oh so that is an x and not a multiplication symbol

- freckles

are you suppose to evaluate the expression for some x value?

- anonymous

@freckles no it's just a multiplication symbol

- freckles

so I had it right a sec ago
\[4^2-2(3 \times 5+1)\]

- freckles

order of operations:
1) grouping symbols
2) exponents
3) mult/div as occurs left to right
3) add/sub as occurs left to right

- freckles

looking at 1) we do have grouping symbols
contained in the grouping symbols is 3(5)+1
we are to do multiplication before addition so
you have to compute 3(5)
and then add 1 on to that
to get the answer for 3(5)+1

- freckles

and you know 3(5)+1 =?

- templeguy

Answer these five questions for five metals

- anonymous

16 @freckles

- freckles

right so we have
\[4^2-2(3 \times 5+1) \\ 4^2-2(15+1) \\ 4^2-2(16)\]

- freckles

now we have exponents subtraction and multiplication

- freckles

according to the order of operations we are to take care of our exponenets first

- freckles

and remember 4^2 means 4 times 4

- IrishBoy123

@Haley123450 :-))

- freckles

\[4^2-2(3 \times 5+1) \\ 4^2-2(15+1) \\ 4^2-2(16) \\ 16-2(16)\]
now only two operations remain
subtraction and multiplication
you are to do the multiplication first
then the subtraction
you should get @templeguy 's answer after completion

- anonymous

I didn't know what to do with the other half because I had 16 but I didn't know if I as supposed to add it multiply it or what. So it was kinda just sitting there

- anonymous

And I totally agree

- freckles

16-2(16)
yes this means we need to multiply 2 and 16 which gives us 32
and so you have
16-32
you can also write this as
-32+16
or
-(32-16)
-(16)
-16

- freckles

anyways i hope you feel better about this problem
