Remember: A tab or an I O U is a written promise to pay later. It runs on trust.
Read and answer
Read the story first, then answer.
Sam and the bakerLong ago, before cards, Sam loved warm buns. Rosa the baker made the best buns in the village, and every bun cost one pretend coin. One Monday Sam had empty pockets, and Rosa said, "Take two buns, and pay me on Friday." She made two chalk marks on a board. On Tuesday Sam took one bun, and on Wednesday three, so the board showed six marks. A list like this is called a tab. On Thursday Sam wrote a note: "I owe you six coins." This kind of note is an I O U. On Friday Sam carried baskets for a neighbor and earned six coins. Rosa counted exactly six, rubbed out the chalk marks and handed back the note. Paying later works because people trust each other.

14 1 + 3 = 4. Tuesday had one bun and Wednesday had three.
22 more 3 − 1 = 2. Wednesday had 3 buns and Tuesday had 1.
36 2 + 1 + 3 = 6 buns at one coin each, so Sam owed 6 coins.
41-C, 2-D, 3-A, 4-B A tab lists what is not paid for yet, and an I O U says I owe you. Each chalk mark is one bun, and paying later works because people trust each other.
