I just want you please ask a high school or primary school math. teacher that:
is 5-2^2=-2^2+5 ?
This is just a simple math. rule... ;)
>My example was bad, my point is that the - in 5-2 is not the same operation as the - in -2. As I see it the - in -2 is NOT an operation at all but is part of the operand of -2 therefore if you square the value of -2 you get 4. The - sign does not mean -1 * 2 it means teh operand of -2 which is not an operation.

>>>5 * 2 + 1 = 10
>>>2 + 1 * 5 = 15
>>>
>>>change the order of operations and the result changes The - in 5 - 2 is NOT the same operation as the - in -2.
>>
>>New arithematic rule? What happened to:
>>
>>1. Simplify all operations inside parentheses.
>>2. Simplify all exponents, working from left to right
>>3. Perform all multiplications and divisions, working from left to right.
>>4. Perform all additions and subtractions, working from left to right.

>>5*2+1 = 10+1 = 11
>>2+1*5 = 2+6 = 8

>>Or did I misunderstand the message in your post?
