### Instruction:
 Mark started the day with 14 buttons. His friend Shane gave him 3 times that amount of buttons. Then his other friend Sam asked if he could have half of Mark’s buttons. How many buttons did Mark end up with?


### Response:
 Shane le dio a Mark 14 x 3 = <<14*3=42>>42 botones. Después de eso, Mark tenía 42 + 14 = <<42+14=56>>56 botones. Luego, Mark dio 56 / 2 = <<56/2=28>>28 botones a Shane. Después de dar algunos de sus botones, Mark quedó con 28 botones.
