25

Explanation:

Always count the number of terms first. For each term there must be a single answer which you will then add or subtract in the last line of working.

There are 3 terms here, so we need 3 answers

#color(blue)((5xx2)) + color(magenta)((6-7)) + color(orange)(16)#
The brackets are not necessary but they illustrate the point of 3 terms.

=#color(blue)10 color(magenta)(-1) +color(orange)16#

=# 10+16-1 = 25#
