Use the order of operations: Going from left to right, first multiplication/division, then addition/subtraction. So, going from left to right, we encounter addition (+), subtraction (-), multiplication(*), and division (/). Using the order of operations, multiplication has higher precedence, so we do that first; i.e., 6 * 5, which is 30. Our equation now becomes . Using order of operations again, we divide 30/2, which is 15, producing the equation . Again, use order of operations to add 7+9, which is 16, giving equation , which simplifies to .
