Hello. I was do the order of operations work and noticed some of the division formulas have no parenthesis on the denominators yet the answers reflect there should be. Maybe its a misunderstanding of the order of ops on my part. confusing. two examples: 70/8+6 equaled 5 and 6/(3-1) equaled 3. Another without parenthesis was 13/5+8=1. should parenthesis be on the denominators to signify they should be added first as without them both are dividing the numerator?
