a. Depreciation on the company's equipment for the year is computed to be $18,000. b. The Prepaid Insurance account had a $8,000 debit balance at December 31 before adjusting for the costs of any expired coverage. An analysis of the company's insurance policies showed that $610 of unexpired insurance coverage remains. c. The Supplies account had a $260 debit balance at the beginning of the year, and $2,680 of supplies were purchased during the year. The December 31 physical count showed $307 of supplies available. d.

Problem 1. Design a circuit with four inputs and one output so that the output is 1 if there are an odd numbers of ones among the input variables, and 0 otherwise. (Use only AND, OR, NOT gates.) Problem 2. Construct a circuit equivalent to the half-adder (from class and in the textbook) using only NAND gates. Use as few NAND gates as you can. Problem 3. Recall from class that we can write all three of AND, OR, NOT in terms of NAND. We can express this in terms of the following logical equivalences for the Sheffer stroke $P \mid Q$. $\sim P = P \mid P$ $P \lor Q = (P \mid P) \mid (Q \mid Q)$ $P \land Q = (P \mid Q) \mid (P \mid Q)$ Write logical equivalences to express $\sim P$, $P \lor Q$, $P \land Q$ in terms of the Pierce arrow $\downarrow$ which represents the NOR operation. Prove your identities using truth tables.
