-4(21)-13 + 94-81[32-27(4)-32]
=-4(21)-13 + 94-81[108]
=(-84)-13 + 94-8748
=-97+ 94-8748
=-3-8748
=-8751

I suck at giving questions though

Isn't It 3561?

Well you did it just a little off, I think???

-4(21)-13 + 94-81[32-27(4)-32] < first part
=-4(21)-13 + 94-81[108] < Its not 108, its a -108 --- [32-108-32] = -76-32 = -108
=(-84)-13 + 94-8748 < Now -81[-108] = +8748
=-97+ 94-8748 < -97 + 94 + 8748
=-3-8748 < -3 + 8748
=-8751 < 8745 - I think

A nice easy question. What are two equations that always give you an odd number no matter what X is.

 

[Sephiroth Reborn]

y=2x+1
y=2x-1
?????

 

[Spirit]

all this math is making my head hurt.*cries*. I don't know the answer

Wtf???

-4(21)-13 + 94-81[32-27(4)-32] = ?

-84 -13 + 94 -81 (-108) =
= -84 -13 + 94 +8748 =
= 97 + 94 + 8748 =
= 191 + 8748 =
= 8939

Hmmmmmmmmmm...

Well, the rule to doing these types of problems is P.E.M.D.A.S or Please Excuse My Dear Aunt Sally. parenthesis, exponents, multiplication, division, addition, subtraction. Following the rule we get:
problem: -4(21)-13+13[(5)(4)-32] -------> -84-13+13(20-32)-----> -84*-12 = 1008

So the lot of ya were wrong!

Check please!

Let me try again...

-4(21)-13 + 94-81[32-27(4)-32] = ?

-4(21)-13 + 94-81[32-27(4)-32] = ? <=> <---------- First part

<=> -84 -13 + 94 - 81 (32 -108 -32) <=> <--------- -4*21 = -84; -27*4=-108

<=> -97 + 94 -81*-108 <=> <------------ -84-13=-97; Cut "32" and "-32" thanks to the comutative property

<=> -3 + 8748 <=> <--------- -97+94=-3; -81*-108= +8748

<=> 8745 <---------- -3+8748 is the same as 8748-3=8745

Different again Now it's the same as Shaggy's!

What's wrong?

-4(21)-13+13[(5)(4)-32]

That's not what you gave us initially

Now, you:

y=2x+1
y=2x-1
?????

The answer is y=|2x-1| <=>

<=> y=2x+1 v y=2x-1

So, does anyone have any more challenges? I'm getting bored
