Can somone help me please?
 

I know this is supposed to be in help forum but i need help real soon please. My math homework is so fucking weird i dont get it. Its (5-0.5)x0.22=?

Im pretttty sure that the parenthesis one is 4.5 and i keep getting :36! Look this is how i do it.

thats how i do it. Ineed help. I know the answers 99 but i have to show work. Please somone help me.

Can't help you buddy. Math hates me almost as much as I hate it. We try to keep our distance from one another as generous as possible.

5 - 0,5 = 4,5
4,5 x 0.22 = 0,99 ???

Yeah i get to that too.

Easy, if the question is- Its (5-0.5)x0.22=?

You do the parenthesis first- which equals 4.5 and then multiply it by 0.22. Therefore the answer would be 0.99. So, the people who posted above me are right.

So, remember, when doing order of operations: BEDMAS.

B-Brackets
E-Exponents
D-Division
M-Multiplication
A-Adding
S-Subtraction

But, division and multiplication could be switched around, which ever comes first on the page. Same with adding and subtracting.

bedmas, thats good. i should remember that.

(a + b) = (b + a)
(a - b) = -1x(b - a)
(a + b)² = (a² + 2ab + b²)
(a - b)² = (a² - 2ab + b²)
(a - b)x(a + b) = a² - b²

If you have a calculator, you might find it easy to turn fractions into float-point decimal values instead. For instance, if you have an equation that looks like 5/6x - 22x = 3, then you can always turn that into 0.83x - 22x = 3 (note: 0.8 is followed by an infinite number of 3's, so just put an overline on top of the 3 to indicate the float value repeats infinitely). So, just subtract 22x from that, and end up with -21.166666...X = 3. So divide both sides with -21.166666..., and get your happy results. Teachers don't seem to appreciate using tons of decimals, but if you can keep those "overlines", it's not faulty in any ways.

All the schools I've been in used

P-Perenthesis
E-Exponents
M-Multiplication
D-Division
A-Addition
S-Subtraction

...right...
Anyway, it's not that simple for me anymore, 'cause I'm a C programmer. Here is my order of operations list.
Brackets, parenthesis, members, member indirection, postincrement, postdecrement
preincrement, predecrement, sizeof, address of, pointer indirection, positive, negative, bitwise NOT, logical NOT
typecasting
Multiplication,division,division remainder
addition,subtraction
bitwise shift left, bitwise shift right
less than,greater than, less than or equal to, greater than or equal to
equal, not equal
bitwise AND
bitwise XOR
bitwise OR
logical AND
logical OR
inline conditional
assignment
sequential evaluation

:eek: :eek: :eek: :eek:
Needless to say, for the most part I just use a lot of parentheiss...

I'll have to go with Wetwired on this, I learned te Pemdas not the other thing, oh well, whatever

You guys dont understand, I KNEW it was .99 because i had a calculator, i have to WRITE IT and i forgot how to use lattice method and im having troubles with traditional, and imt rying to learn traditional. its not just for the schools health of getting my hw in its for me learning. I dont understand how the hell to get there..... Tell me how? ples? And then ill have another problem for u!^_^

oMG thx wewired for that! *gets out his hw and pencil^_^*

And i have another one its like way harder to me ... 9x0.123456789

damn they are smart

wait a minute you said to multiply first????
try this one then

5 * 4 + 3 - 2 * 5 / 4 * 5 + 4

would you just do it accross?? or multiply frst??

We got to make up our own acronym in our class for PEMDAS and it went somthing like "Petting Every Monkey Doesnt Always Suffer"

5 * 4 + 3 - 2 * 5 / 4 * 5 + 4
20 + 3 - 12.5 + 4
14.5

Wetwired ur teh leetestnesssed ^_^ Thankx !

Ok, WetWired, you're helping me with my PreCalculus next semester... if I need help. Oh, and Physics.

Sorry, I've hardly used anything past Algebra since I learned it, so I'm afraid I won't be of much use to you. I took all the way to Calculus, but I'd definately need a refresher before I could help anyone with it.

What the fuck.......its not that hard to multiply....slaynish couldnt do ti on hsi own?
