To solve this problem we want to look at keywords. First, they "put their collection together" which means they add their marbles together. 146 +124 = 270.
Then they "divide them equally" so we are dividing. They are splitting the marbles between the two of them so we are dividing by 2. 270 divided by 2 is 135.
Each kid will get 135 marbles.
