As a sum

(5 × 6) + 0 = 30

• A tally is drawn in fives: four upright strokes, then a fifth stroke struck diagonally across them to close the group. Counting the closed groups in fives is faster and less error-prone than counting every mark.
• Counting the groups in fives gives 5 × 6 = 30, which is 30.
• In other words 30 = (5 × 6) + 0, which is what dividing 30 by 5 tells you: 6 remainder 0.
