Class VI Mathematics worksheet on integers, focusing on addition and subtraction operations with missing signs and answers.

Let's solve each part of Question 1 step by step, using the rules of integers (positive and negative numbers).

---

Rules to Remember:

- Adding a negative number is like subtracting:
$ a + (-b) = a - b $
- Subtracting a negative number is like adding:
$ a - (-b) = a + b $
- Subtracting a positive number is straightforward subtraction.
- When adding two numbers with different signs, subtract their absolute values and keep the sign of the larger absolute value.

Now, let's go through each problem:

---

(i) $-5 + (-6)$
= $-5 - 6$
= $-11$

✔ So: $-5 \boxed{-} 6 = \boxed{-11}$

---

(ii) $7 - (+5)$
= $7 - 5$
= $2$

✔ So: $7 \boxed{-} 5 = \boxed{2}$

---

(iii) $4 - (-4)$
= $4 + 4$
= $8$

✔ So: $4 \boxed{+} 4 = \boxed{8}$

---

(iv) $-4 - (-8)$
= $-4 + 8$
= $4$

✔ So: $-4 \boxed{+} 8 = \boxed{4}$

---

(v) $-3 - (+5)$
= $-3 - 5$
= $-8$

✔ So: $-3 \boxed{-} 5 = \boxed{-8}$

---

(vi) $-5 + (+4)$
= $-5 + 4$
= $-1$

✔ So: $-5 \boxed{+} 4 = \boxed{-1}$

---

(vii) $5 + (+10)$
= $5 + 10$
= $15$

✔ So: $5 \boxed{+} 10 = \boxed{15}$

---

(viii) $8 + (-4)$
= $8 - 4$
= $4$

✔ So: $8 \boxed{-} 4 = \boxed{4}$

---

(ix) $-6 + (+5)$
= $-6 + 5$
= $-1$

✔ So: $-6 \boxed{+} 5 = \boxed{-1}$

---

(x) $6 + (-10)$
= $6 - 10$
= $-4$

✔ So: $6 \boxed{-} 10 = \boxed{-4}$

---

✔ Final Answers:

| Question | Operation | Result |
|--------|----------|--------|
| (i) | $-5 - 6$ | $-11$ |
| (ii) | $7 - 5$ | $2$ |
| (iii) | $4 + 4$ | $8$ |
| (iv) | $-4 + 8$ | $4$ |
| (v) | $-3 - 5$ | $-8$ |
| (vi) | $-5 + 4$ | $-1$ |
| (vii) | $5 + 10$ | $15$ |
| (viii) | $8 - 4$ | $4$ |
| (ix) | $-6 + 5$ | $-1$ |
| (x) | $6 - 10$ | $-4$ |
