1. The problem appears to be a set of arithmetic expressions and equations involving multiplication and subtraction. 2. Let's clarify and solve the first expression: $5 \times 8 = 5$. 3. Multiplying 5 by 8 gives $5 \times 8 = 40$, which is not equal to 5, so this equation is false. 4. Next, consider the expression $45 - 63$. 5. Subtracting 63 from 45 gives $45 - 63 = -18$. 6. The next expression is $9 \times 7$. 7. Multiplying 9 by 7 gives $9 \times 7 = 63$. 8. Then, the expression $-24 - 30$. 9. Subtracting 30 from -24 gives $-24 - 30 = -54$. 10. The expression $555 = 333$ is a false equality since 555 is not equal to 333. 11. The last expression is $39 + 52 = 1 \times 3$. 12. Adding 39 and 52 gives $39 + 52 = 91$. 13. Multiplying 1 by 3 gives $1 \times 3 = 3$. 14. Since 91 is not equal to 3, this equation is false. 15. Summary: The only correct arithmetic operations are the calculations themselves, but the equalities given are mostly false.
