Step-by-step explanation:
Answer: One possible way: 123 - 45 - 67 + 89
Step-by-step explanation: The goal is to get 100, using all of the following numbers: (1,2,3,4,5,6,7,8,9)
We can merge numbers to get 100.
123 - 45 - 67 + 89 (We used every number once)
Lets solve from left to right.
123 - 45 = 78. 78 - 67 = 11. 11 + 89 = 100.
3 = 3
10=2 x 5
15=. 5 x 3
lcm=2x5x3=30
