#18#

Order of operations: parentheses/brackets, exponents, multiplication/division, and addition/subtraction

Since there are no parentheses, the exponent has to be evaluated first:

#25-8*2+3^2#

#25-8*2+9 rarr# Next comes multiplication

#25-16+9 rarr# Now there's just subtraction and then addition (follow the order in which it is written)

#9+9#

#18#
