Common core is about 20 years after I went to school. Is there something in common core that teaches about the scope of denominators?

230 is 230/1. 220 is 220/1.
230 is 230/1. 220 is 220/1.
230 is 230/1. 220 is 220/1.
Yes, that's not the ambiguity. The ambiguity is whether the two is a denominator of the whole rest of the equation, e.g.:
230/1 - 220/1 x 1/2
Or, whether 1/2 is a numerator, e.g.:
230/1 - 220/1 x (1/2)/1
The ambiguity arises because of typing the entire equation inline without parantheses. In proper notation the difference is between:
This (pic8.co)
and
