I'll give you a question, please answer with step-by-step reasoning process.
Lexie and Tom went apple picking. Lexie picked 12 apples and Tom picked twice as many apples. How many apples did they collect altogether?

Tom picked 12 x 2 = 24 apples.

Altogether, they picked 12 + 24 = 36 apples.

So, the final answer is 36
