1. **State the problem:** We have multiple subtraction problems and word problems involving subtraction and division. 2. **Subtraction problems:** To subtract two numbers, subtract the digits starting from the right (units place) moving left, borrowing if necessary. 3. **Example subtraction:** For $100 - 8$, subtract 8 from 0, borrow 1 from the tens place, so $100 - 8 = 92$. 4. **Word problem 1:** Your machine uses 5000 watts, and your fan uses 1500 watts. Total watts used = $5000 + 1500 = 6500$ watts. 5. **Word problem 2:** Marine turtles lay about 10 eggs at a time. If the turtle laid 70 eggs, number of times laid = $\frac{70}{10} = 7$ times. 6. **Word problem 3:** Vet gave shots to 5 chickens costing 150 total. Cost per chicken = $\frac{150}{5} = 30$. 7. **Additional subtraction examples:** - $2050 - 760 = 1290$ - $2050 - 718 = 1332$ - $2050 - 100 = 1950$ 8. **More subtraction examples:** - $800 - 243 = 557$ - $901 - 443 = 458$ - $81936 - 400 = 81536$ 9. **Summary:** Use borrowing for subtraction when needed, add watts for total power, divide total eggs by eggs per laying for number of times, and divide total cost by number of chickens for cost per chicken. **Final answers:** - $100 - 8 = 92$ - $100 - 77 = 23$ - Total watts = 6500 - Turtle laid eggs 7 times - Cost per chicken = 30 - $2050 - 760 = 1290$ - $2050 - 718 = 1332$ - $2050 - 100 = 1950 - $800 - 243 = 557$ - $901 - 443 = 458$
