This part covers arithmetic once sequential elements are in place. Adder families trade depth against area, and multiplier stages run from recoding through compressor trees to the final add. Sharing then reuses operators across operations only where the mux cost wins.

5 | Ripple, lookahead, select, and prefix adders as depth-area trade-offs. | 40 min | |
5 | Booth recoding, compressor trees, and the final adder. | 40 min | |
4 | Sharing adders across operations, and when the mux costs more. | 32 min |
Off-by-one slips in depth and node counts are invisible in symbols but fail on 4-bit and 8-bit cases. The Adders and Carry Structures topic builds those checks.
