Applying the distributive property, this becomes (90,000 × 5) - (3 × 5). The first part, 90,000 × 5, equals 450,000. The second part, 3 × 5, equals 15. Subtracting 15 from 450,000 yields 449,985.

Alternatively, performing the multiplication directly:

5 × 7 = 35 (write down 5, carry over 3)

5 × 9 = 45 + 3 (carry-over) = 48 (write down 8, carry over 4)

5 × 9 = 45 + 4 (carry-over) = 49 (write down 9, carry over 4)

5 × 9 = 45 + 4 (carry-over) = 49 (write down 9, carry over 4)

5 × 8 = 40 + 4 (carry-over) = 44 (write down 44)

Combining these digits in order from right to left results in 449,985. The number 449,985 is an integer. The operation 89997×5 is a fundamental arithmetic problem encountered in basic mathematics education.
