Question 58598: Okay I am an 8th grade student and I am (sadly) learning algebra, At the beggining I understanded everything but now... I am learning all kinds of stuff and I am honestly mixed up... Like we are learning BEDMAS (order of operation) with algebra...
B:Bracket
E:Exponent
D:Division
M"Multiplication
A:Addtion
S:Substraction.
And then I learned the negatives and positives, and the common (like) terms... and then I learned all these things I am totally lost...
Here is one of my problems:
-(10x(exponent 2))+(5xy-9)-(8x(exponent 2)+18xy)= ???
Ohhhhhh I am totally lost PLEASE HELP ME!!!
Thank you for your time and hope to get your answer soon...
Thanks again, Krysta Lessard 8th grade Canada

I LEARNED THE SAME WAY, BUT IT WAS P.E.M.D.A.S.
P- PARENTHESIS
E- EXPONENTS
M- MULTIPLICATION
D- DIVISION
A- ADDITION
S- SUBTRACTION
-(10x(exponent 2))+(5xy-9)-(8x(exponent 2)+18xy)=
-10x^2 - 5xy + 9 - 8x^2 - 18xy
-18x^2 - 23xy + 9
