WHOA! Now we really need PEMDAS Parenthesis , Exponents , Multiplication, Division, Addition, Subtraction ... brackets are also considered part of the parenthesis option which is to do that section first. Let's start at the denominator since that's easier

4. UsukiDoll

so we have our P which is () we need to do that first . what is 8-2?

6

6. UsukiDoll

yes... so now our denominator has 7(6)+4

7. UsukiDoll

E isn't showing up so we move on... we do have M.. what is 7 x 6?

8. anonymous

17

9. UsukiDoll

ummm we are multiplying... 7 x 6 = 42

10. UsukiDoll

so now our denominator is 42+ 4 there is no D, so we move to A which is addition... what is 42+4

46

12. UsukiDoll

yes! so our denominator is 46... now let's work on the numerator .. if I remembered correctly whenever there is a bracket and parenthesis at the same time.. the bracket portion is done first

13. UsukiDoll

$6[5(3-9)-1]+2$

14. UsukiDoll

I see brackets so we need to tackle that first . what is 3-9?

15. anonymous

6

16. UsukiDoll

close.. but we have a positive number 3 and a negative number 9 our positive number is too small, so we end up with a negative number 6 It's like you ordered $9 food, but you only have$3, you owe \$6 dollars -6

17. UsukiDoll

$6[5(-6)-1]+2$ so we have no exponents.. we move on to multiplication what is 5 x (-6)

18. anonymous

-30

19. UsukiDoll

hi.,,, and yes that's correct

20. UsukiDoll

$6[(-30)-1]+2$ we don't have addition so we move on to subtraction . what is -30-1

21. anonymous

-31

22. UsukiDoll

yes. $6[-31]+2$ so now we have multiplication which is -31 x 6

23. UsukiDoll

-31 x 6 is -186 so -186 +2 which is the only thing to solve and uses addition -186+2 = -184 and our denominator is 46 . We can reduce this $\frac{-184}{46}$

24. UsukiDoll

wow this works actually nicely... apparently since the greatest common factor is 46 we have -4 -184/ 46 = -4 and 46/46 = 1 so -4/1 = -4
