Wikipedia's Postfix notation gives an example of "4 * (5 + 8)" becoming "5 8 + 4 *". Using this concept, plus finishing with the $-2$ at the end, I believe one valid way to put $24 * (5 + 6) - 2$ into postfix notation would be
$$5 \; \, 6 \, + \, 24 \, * \, 2 \, \, - \tag{1}\label{eq1A}$$
$24 * (5 + 6) - 2$
first you need to remember the order of operations, basicaly everything on () is made first then multiplication, division and then sum and subctraction so in that case 5 + 6 is made first you start on 24 there a multiplication but since there start of ( you don't do the operation yet you get the sum 5 plus 6 wich lead to
24 5 6 +
now since ) ended and you have a subtraction wich is lower priority than * you do the multiplication
24 5 6 + *
now you just finish subtracting 2 leading to
24 5 6 + * 2 -
you answer is complet diferent from what you want
24 5 * 6 2 + -
leads to
$24*5 - (6 + 2)$
