Let’s solve each addition problem step by step.

---

(i) 12 + 15 + 13

First, add 12 and 15:
12 + 15 = 27

Then add 13 to that result:
27 + 13 = 40

✔ So, (i) = 40

---

(ii) 23 + 33 + 11

Add 23 and 33 first:
23 + 33 = 56

Now add 11:
56 + 11 = 67

✔ So, (ii) = 67

---

(iii) 36 + 10 + 12

Add 36 and 10:
36 + 10 = 46

Then add 12:
46 + 12 = 58

✔ So, (iii) = 58

---

(iv) 31 + 52 + 15

Add 31 and 52:
31 + 52 = 83

Then add 15:
83 + 15 = 98

✔ So, (iv) = 98

---

(v) 9 + 8 + 2

Add 9 and 8:
9 + 8 = 17

Then add 2:
17 + 2 = 19

✔ So, (v) = 19

---

Final Answer:
(i) 40
(ii) 67
(iii) 58
(iv) 98
(v) 19
