1. The problem asks to calculate the product of $14,400,000$ and $999$. 2. Recognize that multiplying by $999$ is the same as multiplying by $(1000 - 1)$. 3. Rewrite the expression: $$14,400,000 \times 999 = 14,400,000 \times (1000 - 1)$$ 4. Distribute the multiplication: $$14,400,000 \times 1000 - 14,400,000 \times 1$$ 5. Calculate each term: $$14,400,000 \times 1000 = 14,400,000,000$$ and $$14,400,000 \times 1 = 14,400,000$$ 6. Subtract the second term from the first: $$14,400,000,000 - 14,400,000 = 14,385,600,000$$ 7. Therefore, the product $$14,400,000 \times 999 = 14,385,600,000$$.
