Question

How can you express 499 to find the product 499×5 using mental math explain

Answer 1

Answer:

So the answer would be 2495.

Step-by-step explanation:

We can write 499 as  500 - 1

Because we can easily multiply 500 to 5 compare to 499 to 5.

So product of 499 × 5 = (500 - 1) × 5

                                  = 500 × 5 - ( 1 × 5 = 5 )

                                  = 2500 - 5 = 2495

So the answer would be 2495.

Answer 2

499 = 500 - 1
(500-1)(5) = 2500 -5 = 2495
