funny!! are you sure, cos what i just stated follows the order of B.O.D.M.A.S accordinlly, mistake ppll made is not dissolving all the "B" first before any other operation

2 - [1 - (1 - [2 - 3] - 2) + 3]

Solve d 1 in d bracket 1st, 2-[1-(1-[-1]-2)+3],
open d bracket gradually.....
2-[1-(1--1-2)+3]
2-[1-(1+1-2)+3]
2-[1-(0)+3]
2-[1-0+3]
2-[1-+3]
2-[1-3]
2-[-2]
Open d last bracket

As a 1st Class Electrical Electronic Engr from a federal University, the answer is +4. Applying the fundamental mathematics BODMAS and get it. One 500Levels mathematician fall hand big time.

OP, I feel the expression is wrong in the first place. Reason, a smaller bracket can not enclose a bigger bracket. I mean (1-[2-3]-2) is wrong because this sign ( ) is junior to [ ] in Mathematical expressions. And in Mathematics, you solve the smaller bracket before moving to higher bracket. So, how did you solve this, (1-[2-3]-2) ?

Re: Solve This Simple Maths Question If You Can!:::::::::::::::::::::::::::::::::::: by managermahmud: 8:05am On Dec 08, 2014

The answer is 4!

[1-0+3] is not and can neva be = 4
Because -*+= -
Therefore
=> 1-3=-2

So,
2-[-2]=4
Thr4, d ansa is 4

Re: Solve This Simple Maths Question If You Can!:::::::::::::::::::::::::::::::::::: by Nobody: 8:08am On Dec 08, 2014

2 - [1 - (1 - [2 - 3] - 2) + 3]

= 2 - 3 = - 1

= 1 + 1 - 2 = 0

= 1 - 0 + 3

= 2 - 4

= - 2

Start from the innermost bracket, bodmas.

From the point of 1 - 0 +3 above, applying BODMAS, we'll have to solve the 0 plus 3 part first which gives 1 - 3=-2. Inserting the 2- outside the bracket gives 2-(-2) =4. My answer is 4. @OP, come solve the thing abeg

Re: Solve This Simple Maths Question If You Can!:::::::::::::::::::::::::::::::::::: by PCCOLLYN: 8:23am On Dec 08, 2014

2 - [1-(1-[2-3]-2)+3]

Using BODMAS

2 - [1 - (1 - [-1] -2) + 3]

The absolute value[] of any number is the unsigned/positive value of the number

= 2 - [1 - (1 - 1 - 2) + 3]

= 2 - [1 - (-2) + 3]

= 2 - [3+3]

= 2 - 6

= 4
