Math. Love it or hate it. I, for one, happen to HATE it. From the very pit of my soul. ah.
So this is sorta embarrassing for me but i am gonna just swallow my pride and get on with it.
I was doing this problem for literally 1 hour. ONE HOUR!
-5(-7+3*6-4)^2 {the little "^2" means "squared"}
looks easy enough, right? WRONG.
well here were my steps.
do do doo... (ps i will put my thoughts on the side)
-5(-7+3*6-4)^2 great. sydney, you CAN do this. *breathe*
-5(-7+18-4)^2 okay one step down...
-5(11-4)^2 wow this is easier then it looks. hmm
-5(7)^2 almost done, see sydney, you can do it.
-35^2 almosttttttt thereeeeee
1,225. *looks at answer* *WRONG* ahhhhh what did i do wrong?!?!
okay let's try it again.
this time i'll double check EVERY thing with a calculator.
-5(-7+3*6-4)^2 *checks to make sure 3*6 really does =18*
-5(-7+18-4)^2 it does. *checks to make sure -7+18=11*
-5(11-4)^2 it does. *checks to make sure 11-4 really is 7*
-5(7)^2 thats correct. where am i going wrong??
-35^2
1,225. still.the.same.darn.answer. argh.
well i'm trying it again. this time a bit different.
-5(-7+3*6-4)^2
-5(-7+18-4)^2
-5(11-4)^2
-5(7)^2
-5(14)
-70. not.even.close.
(can anyone see my mistake yet?)
well apparently 7^2 does NOT =14.
7^2 equals 49. ahhhhhhhhhh the ONLY one i did not check because i was soo sure of my math skillz.
and now it checks out.
-5(-7+3*6-4)^2
-5(-7+18-4)^2
-5(11-4)^2
-5(7)^2
-5(49)
-245
yeah, i stink at math. poor me.
thanks for reading.

Soooo glad I don't have to do that kind of math anymore.
Although I do wish it came easier. It's just so. much. effort. No?!
Perhaps if you master your math skillz, the cupcakes will follow? Heeheehee.
YAY my first comment. (other then family) (:
thank you ! <3
and yes, i will probably get better at making cupcakes faster then learning this stupid math.
Sydney,
You had the wrong answer because you forgot to use the order of operations rule! PEMDAS - parentheses, exponents, multiplication, division, addition, subtraction. In the first example of your post, you did everything right until you multiplied the 7 by -5. Pemdas says that after the parentheses, then you handle the exponent!
Math is the BOMB!
no it is NOT. but im glad to have math geeks like you to help a sister out. (:
Math still gets me into trouble...
