You use / for divide.

Order of operations (the correct method), the answer is 7.

In the order it is presented, the answer is 1.

I had a ticket from McDonald's monopoly game to cash in and they made me answer a skill testing question.  I was pleasantly surprised to see them put things in brackets that needed to be done first so that people would get the correct answer.  So your equation would have been:

6 - (1X0) + (2/2) = ?

I believe the answer is 7.
Because there are no indicators, you use the basic order of operation: multiplication, division, addition, subtraction.

I hope I remembered this right.

My Dear Aunt Sally.  The answer is undefined because multiplying by zero is undefined.  Nothing can be added to an undefined number.

Actually it is dividing be zero that is undefined. Multiplying anything by zero equals zero.

According to the order of precedence, the answer is indeed 7.

I think it would be 1
6 minus 1 is 5,  5 times 0 is 0.  0 plus 2 is 2.  Two divided by 2 is 1.

I (and DH) learned absolutely unquestionably without parenthesis ones does math in order left to right.  So as written the answer is 1.

If written 6 - (1X0) + (2/2) it would be 7.
