We can use the distributive property of multiplication to simplify the calculation of 999 × 18 by breaking down 18 into smaller factors that are easier to multiply by 999:
999 × 18 = 999 × (10 + 8)
Using the distributive property of multiplication, we can distribute the 999 to each term inside the parentheses:
999 × (10 + 8) = (999 × 10) + (999 × 8)
Now, we can simplify each multiplication:
999 × 10 = 9990
999 × 8 = 7992
Finally, we add these two products together to get the result:

Answer:17982
999*18
=(1000-1)*18 (Using the distributive property)
=(1000*18)-(1*18)
= 18000-18
= 17982
Answer:
17982
Step-by-step explanation:
We can use the distributive property of multiplication to simplify the calculation of 999 × 18 by breaking down 18 into smaller factors that are easier to multiply by 999:
999 × 18 = 999 × (10 + 8)
Using the distributive property of multiplication, we can distribute the 999 to each term inside the parentheses:
999 × (10 + 8) = (999 × 10) + (999 × 8)
Now, we can simplify each multiplication:
999 × 10 = 9990
999 × 8 = 7992
Finally, we add these two products together to get the result:
999 × 18 = (999 × 10) + (999 × 8) = 9990 + 7992 = 17982
Therefore, 999 × 18 is equal to 17982.
