So I know the equation is ambiguous, but giving it my best shot following PEMDAS/BODMAS as closely as possible:
9 - 3 ÷ 1/3 + 1
9 - 9 + 1
0 + 1
1
Looking around at other posts this seems to be the general consensus, thankfully! I know there are parts I’m not entirely clear on but I know those will get covered later when we start looking at proper ‘grammar’.
