1. **State the problem:** Simplify the expression $4 \times 3 \times 4 \times 30 - 8xj - 7 - 9 + y + 1r$. 2. **Multiply the constants:** Calculate $4 \times 3 = 12$, then $12 \times 4 = 48$, and finally $48 \times 30 = 1440$. 3. **Rewrite the expression:** Now the expression is $1440 - 8xj - 7 - 9 + y + 1r$. 4. **Combine like terms:** Combine the constants $-7 - 9 = -16$. 5. **Final simplified expression:** $$1440 - 8xj - 16 + y + r$$ This is the simplified form, combining all constants and leaving variables as is because they are unlike terms.
