Which strategy can be used to multiply 6 198 mentally?

Answer 1

Assuming you meant 6 x 198... Do a mental sum for 6 x 200 (1200) then subtract 6 x 2 (12) to give you 1188.

Answer 2

Well, honey, there's no magic trick here. Just break it down into smaller, more manageable chunks. Start by multiplying 6 by 100 to get 600, then multiply 6 by 90 to get 540, and finally add those two results together to get 600 + 540 = 1140. Easy peasy lemon squeezy.
