B.To solve the problem 3,999,999 * 1,111,1111 you can use one of two strategies. 4.You can multipl

4) Might be mnemonic

5) Thinking estimate

Ignore my previous post. I just did some more research.

Algorithms are systematic procedures that always produce solutions to problems. In an algorithm, a specific sequence of thought or set of rules is followed to solve the problem. Algorithms can be very time-consuming. In your example, you could, however, use a heuristic to solve the problem: round the numbers to 4,000,000 1,000,000, multiply 4 1, and add the appropriate number of zeros (000,000,000,000). Although simpler and faster, this heuristic approach yields a less accurate solution than that produced by the algorithmic approach.

Hope this helps! Please mark as solved
