First operation is the calculation within the brackets.

Explanation:

Checking the formatting of the question in edit mode shows that within the brackets we have (2+54xx6) and not (2+54.6) as I first assumed.
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Given:" "63-(2+54xx6)-:5

Brackets first:

Within the brackets

Multiply before add ->color(brown)((2+54xx6))color(blue)(->(2+324))

color(brown)(63-(2+324)-:5)" "color(blue)(->" "63-326-:5

Multiply/divide before add/subtract

color(brown)(63-326-:5)color(blue)(" "->" "63-65.2

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
"So "color(brown)(63-(2+54xx6)-:5color(blue)( = -2.2)
