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

= $209$
