Hilton had a box of 26 marbles that he was playing with.  He found 6 marbles while he was playing, but afterward realized that he had lost 10 marbles.  Lori felt bad and gave Hilton twice as many marbles as he lost.  How many marbles did Hilton have in the end?
Hilton had 26 marbles + 6 marbles - 10 marbles = <<26+6-10=22>>22 marbles.
Lori gave Hilton 2 * the 10 marbles that he lost = <<2*10=20>>20 marbles.
In total Hilton had 22 marbles + 20 marbles = <<22+20=42>>42 marbles.
