Quick Example

Imagine you have six bundles of ten rupees each. If you count all the money together, you will have sixty rupees. This is how sixty looks when written: 60.

Worked Example

Step-by-Step

Let's find out what happens when we add 1 to fifty-nine.

Step 1: Start with the number fifty-nine, which is 59.

---

Step 2: Add 1 to 59. So, 59 + 1.

---

Step 3: When you add 1 to 9, you get 10. Write down 0 in the ones place and carry over 1 to the tens place.

---

Step 4: In the tens place, you have 5, and you carried over 1. So, 5 + 1 = 6.

---

Step 5: Write down 6 in the tens place.

---

Answer: The number you get is 60. So, 59 + 1 = 60.
