i wish i could read minds too :p

3. anonymous

Thank you soo much @templeguy

4. anonymous

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

5. freckles

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

6. freckles

oh is that one x a multiplication sign

7. freckles

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

8. freckles

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

9. freckles

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

10. freckles

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

11. freckles

so 3(5)+1=?

12. anonymous

$4^{2}-2(3x5+1)$

13. freckles

oh so that is an x and not a multiplication symbol

14. freckles

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

15. anonymous

@freckles no it's just a multiplication symbol

16. freckles

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

17. 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

18. 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

19. freckles

and you know 3(5)+1 =?

20. templeguy

Answer these five questions for five metals

21. anonymous

16 @freckles

22. freckles

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

23. freckles

now we have exponents subtraction and multiplication

24. freckles

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

25. freckles

and remember 4^2 means 4 times 4

26. IrishBoy123

@Haley123450 :-))

27. 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

28. 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

29. anonymous

And I totally agree

30. 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
