Answer 2

Let's solve the given arithmetic expressions step by step:

1. $1000 - 48 \times 4 - 114 \div 2$:

   $$= 1000 - (48 \times 4) - (114 \div 2) \quad \text{(Perform multiplication and division first)}$$
   $$= 1000 - 192 - 57 \quad \text{(Perform the remaining subtraction)}$$
   $$= 751$$

2. $58 \times 8 + 73 \times 5 - 427$:

   $$= (58 \times 8) + (73 \times 5) - 427 \quad \text{(Perform multiplication first)}$$
   $$= 464 + 365 - 427 \quad \text{(Perform addition and subtraction)}$$
   $$= 402$$

3. $39 \times 5 + 47 \times 9$:

   $$= (39 \times 5) + (47 \times 9) \quad \text{(Perform multiplication)}$$
   $$= 195 + 423 \quad \text{(Perform addition)}$$
   $$= 618$$

4. $900 - (158 + 140) \div 2$:

   $$= 900 - ((158 + 140) \div 2) \quad \text{(Perform addition and division first)}$$
   $$= 900 - (298 \div 2) \quad \text{(Perform division)}$$
   $$= 900 - 149 \quad \text{(Perform subtraction)}$$
   $$= 751$$
