Braggs · Answer 1

Since 99=100-1,

we use the distribution property,

6 (99) = 6 (100-1) = 600-6 = 594

With minimum practice, the technique can be mastered in a short time.

For example, 15*998 = 15 (1000-2) = 15000-30=14970

Remington Sheppard · Answer 2

99 is 1 less than 100.

(100-1) * 6

100*6=600

-1*6=-6

600-6 = 594

Answer: 594
