#1div1-1xx3=color(red)(-2)#

Explanation:

Using the standard rules (sometimes referred to as PEDMAS)
multiplication and division are always done (assuming no parentheses) before addition and subtraction.
So
#color(white)("XXX")1div1-1xx3#
should be evaluated as
#color(white)("XXX")(1div1) - (1xx3)#

#color(white)("XXX")=1 - 3#

#color(white)("XXX")=-2#
