minus-squareAtomic@sh.itjust.workslinkfedilinkarrow-up0·2 months agoNo… just no. All you’ve done is managing to confuse yourself. What you want it to say is 6÷(2(2+1)) = 6÷6 = 1 But what you actually wrote is (6÷2)2(2+1) = 36÷2 = 18 Adding a space between the ÷ and 2(2+1) is not a replacement for a parentheses.
minus-squareremon@ani.sociallinkfedilinkarrow-up0·2 months agoThe precedences go like this: parentheses > exponents > (multiplication = division) > (addition = substraction) If you encounter operators with the same precedence (like multiplication and division) you go by the order they appear in the equation, left to right. That is how it works.
