How do you get 100 using 1,2,3,4,5,6,7,8,9?

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.

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.
