Actually this is wrong.... The correct term for the order of operations is not PEDMAS it is BEDMAS which stands for:

Brackets,Exponents,Divison,Multiplication,Addition, Subtraction

so the solution would be

6/2(1+2)

Do brackets first:
6/2(3)

then exponents:
there isnt any so this step can be skipped

then division:
6/2(3)=
3(3)

then multiplication
3*3=9

so the answer is 9

so for 2+3*(0-2(6-5)) would equal, starting with the left bracket first:

2+3*(-2(1))=
2+3*(-2)=
2 + (-6)=


the answer is -4
