Why keep the brackets?
Short answer. Without them the meaning changes.
Which direction do you work?
From the inputs on the left towards Q.
Label each gate
| Gate | Inputs | Output |
|---|---|---|
| NOT | A | NOT A |
| OR | B, C | B OR C |
| AND | both | Q |
Remember
| Label every gate output |
| Keep the brackets |
Can you read a circuit like a sentence? Label each gate, left to right. NOT gives NOT A. OR gives B OR C. AND joins them: NOT A AND, in brackets, B OR C. Two rules. Label every output. Keep the brackets.
