Well my strategy to reach the closest number to 100 is to find a multiplication equation that you think will work and think about it. When you think about it the strategy's point is when your top number is close to 100 try to multiply it by a small single digit number.Then when your top double digit number is low try to multiply it by a high single digit number. With this strategy your answer is likely to be correct. Another way is if possible think of one of the two digit numbers that can be made but also it has to be a number that when you multiply it by a single digit number the answer is 100.Now if your last number is close to the number you need to multiply with the number you made and the double digit number you created out of the combinations is around less than 35 or less than 45 you can try multiplying those numbers.
