#12+2xx10^2−6-:2=209#

Explanation:

We should use the order of operations given by PEMDAS, first starting with Parentheses (none here), then Exponents, Multiplication, Division, Addition and finally Subtraction (last two too are not applicable here).

#12+2xx10^2−6-:2# - first solving exponents

= #12+2xx100−6-:2# - now multiplication

= #12+200−6-:2# - then division

= #12+200−3# - then addition

= #212−3# - and finally subtraction

= #209#
