Value of $987 \times 999$ Calculation

To find the value of $987 \times 999$, we can use a simplification technique by rewriting $999$ as $1000 - 1$. This allows us to use the distributive property for easier calculation.

Calculation Steps

1. Rewrite the expression using $999 = 1000 - 1$:

   $ 987 \times 999 = 987 \times (1000 - 1) $

2. Apply the distributive property ($a \times (b - c) = a \times b - a \times c$):

   $ (987 \times 1000) - (987 \times 1) $

3. Perform the multiplications:

   $ 987000 - 987 $

4. Perform the subtraction:

   $ 986013 $

Thus, the value of $987 \times 999$ is $986013$.
