[sachet100 1,020]

Are you having problem solving a Math question :o  OR Math homework ? Then here you can ask Math questions ;)  . Me or other people can solve your question. Feel free to ask any Math related questions. other people who knows Math can help.

 

Someone can ask the question like this:

2x - 4 = 10

 

Then the people who know will solve it like this:

2x-4+4=10+4

2x=14

2x/2 = 14/2

x= 7

 

Please no discussion except Math. Please do not flood.

Ok....

 

A question which i was slightly confused

 

3.58^x-2 = 5.38 :)

[FaaiqBilal1 795]

Ok....

3.58^x-2 = 5.38 :)

are you sure the question is correct? It would make sense if it were 3.58^x-2 = 3.58

I'd also recommend trying Wolfram Alpha, it answers practically all maths problems, and shows alternate solutions/workings.

and it has the DEFINE search. Type "DEFINE" "word" without speech marks and it will define the word for u

(X³+b³) = ?

 

No cheating :)

[sachet100 1,020]

(X³+b³) = ?

 

No cheating :)

That's so easy. let me so u how its done:

x³ + b³ = (x + b)(x² – xb + b²)  This is a simple formula to calculate this type of question.

2 + 2 - 2/₂ x 2 = ?

 

It is easy :mellow:

1+1=?

[7919zola 252]

Basic Algebra ==>

 

x + 2y - 3z + 4w = 12

2x + 2y - 2z + 3w = 10

y + z = -1

x - y + z - 2w = -4

 

Solve for each individual variable.  :P

1+1=?

1=-1

 

Removed the =. What is left: 1-1

 

Push in the ends of the tips of both digits. What is left: l-l

 

Search. What sums up: l-lero

 

Oh, almost forgot, the = sign. Well. Donate it as charity.

How do you divide Integers...?

2 + 2 - 2/₂ x 2 = ?

Pfffttt, 7 m8.

 

Basic Algebra ==>

 

x + 2y - 3z + 4w = 12

2x + 2y - 2z + 3w = 10

y + z = -1

x - y + z - 2w = -4

 

Solve for each individual variable.  :P

When I was in school, I used to do each one in almost 30 sec, my mind is so rusty now xD

2 + 2 - 2/₂ x 2 = ?

 

It is easy :mellow:

we need to use BEDMAS rule.  Brackets,Exponents,division,multipication,addition and then subtraction.

2+2-2/2x2

2+2-1x2

2+2-2

4-2
