well order of operations is parenthesis but we have none then exponents so :
22 + 8 - 36 ÷ 2 x 3
next is multiplication and division. since there is more.than one we go left to right with the ones we have so:
22 + 8 - 18 x 3
22 + 8 - 54
Now we do addition and subtraction and go left to right since more.than 1
30 - 54
-24 is the answer
