i know that

Lv = Av*1.84*10^8/[Vb*1728*(Fb/0.159)^2] - 0.823*sqrt(Av)

but does that mean (Av*1.84*10^8) or Av*1.85*[(10^8)/(Vb*1728*(Fb/0.159)^2)] or are they the same?? (sorry i'm kinda out of it and i'm rusty on my order of operations lol)

BEDMAS ...

Step 1 - Brackets
Step 2 - Exponents and Roots
Step 3 - Division and Multiplication
Step 4 - Addition and Subtraction

wow... I havent heard that in such a long time... LOL

(Av*1.84*10^8) or Av*1.85*[(10^8)/(Vb*1728*(Fb/0.159)^2)]

those aren't the same (1.84 & 1.85)...off by10^6...

you're saying is:
(A * B * C)/D

the same as

A * B * C/D

ex:

if A=1, B=2, C=3, D=4,
(1 * 2 * 3)/4 = 6/4 = 3/2 = 1.5
(1 * 2 * 3/4) = 2 *.75 = 1.5

also, when you divide by a number, you invert & multiply

so (A * B * C) / D =

A * B * C * 1/D

so you can say A/D or B/D or C/D times all the rest..

yea PEMDAS is way cooler. same thing but you remember by "Please Excuse My Dear Aunt Sally".
