# Can someone explain the logic diagram for the Boolean expression NOT A OR B AND C

An IB question requests: Construct the logic diagram for the Boolean expression NOT A OR B AND C.

The question is assuming that the operators precedence goes $$NOT \rightarrow AND \rightarrow OR$$, which is pretty standard for boolean logic.
Hence the proper parathensization would be $$\text{((NOT A) OR (B AND C))}$$, which correspods to the correct diagram, whereas the partial credits corresponds to $$\text{(((NOT A) OR B) AND C)}$$, which would just be a left to right evaluation of the operators.
