Answer:

The addition

Explanation:

Order of evaluation:

Parentheses (none in this case)
Exponentiation: #4^2#
Division and Multiplication: #6/2# (no multiplication)
Addition and Subtraction: there is a minus and a plus
#color(white)("XXX")#-when there are multiple operations at the same level
#color(white)("XXX")#they are performed from Left to Right.
#color(white)("XXX")#Since the minus appears to the left of the plus
#color(white)("XXX")#the minus occurs first (and the plus last).
