Below is an instruction that describes a task. Write a response that appropriately completes the request in German. Please answer in German.

### 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:
 Mark begann mit 14 Knöpfen.
Shane gab ihm das Dreifache der Anzahl an Knöpfen, also 3 * 14 = <<3*14=42>>42 Knöpfe.
Mark hatte insgesamt 14 + 42 = <<14+42=56>>56 Knöpfe.
Sam bat um die Hälfte von Marks Knöpfen, also 56 / 2 = <<56/2=28>>28 Knöpfe.
Mark hatte am Ende 28 Knöpfe.
