Corrected answer

#" "16-:4xx2-7" " =" " 1#

Explanation:

Using strict application of process

P#-># Parenthesise (brackets)
E #-># Exponents (powers)
M #-># Multiply
D #-># Divide
A #-># Add
S #-># Subtract

I am advised that it is better to write this as

P-E-MD-AS as multiply and divide have the same priority. As do add and subtract.

Given:#" "16-:4xx2-7#

So reading left to right

#=>[(16-:4)xx2]-7#

#=>[4xx2]-7#

#=>8-7 = 1#
