Arrange the following numbers in ascending and descending order and fill in the missing integers on number lines.

Here are the solutions to the problems:

1. Arrange the following numbers in ascending order (smallest to biggest):

a) Given: $-2, 0, -5, 4, 3, -1$

$$\boxed{-5, -2, -1, 0, 3, 4}$$

b) Given: $16, -2, -35, 68, -10$

$$\boxed{-35, -10, -2, 16, 68}$$

c) Given: $-25, 100, -50, 75, -100, 90, -1000$

$$\boxed{-1000, -100, -50, -25, 75, 90, 100}$$

d) Given: $37, -13, -45, -24, -19, 28, 8, 11, 2$

$$\boxed{-45, -24, -19, -13, 2, 8, 11, 28, 37}$$

e) Given: $93, -34, -20, 21, -44, 9, -2, 46, 59$

$$\boxed{-44, -34, -20, -2, 9, 21, 46, 59, 93}$$

2. Arrange the following numbers in descending order (biggest to smallest):

a) Given: $-5, -31, 21, -51, 42, -36, 5, 39, -41, -71, 31, 86$

$$\boxed{86, 42, 39, 31, 21, 5, -5, -31, -36, -41, -51, -71}$$

b) Given: $33, -54, 44, -55, -38, 62, 51, -32, -73, -66, 18$

$$\boxed{62, 51, 44, 33, 18, -32, -38, -54, -55, -66, -73}$$

c) Given: $-41, -23, -31, 40, -21, 2$

$$\boxed{40, 2, -21, -23, -31, -41}$$

d) Given: $-56, 37, 23, 10, -31, 32, 31, 36$

$$\boxed{37, 36, 32, 31, 23, 10, -31, -56}$$

e) Given: $4, -9, 17, 7, 10, -2, -14, -6, -13, 9, 12$

$$\boxed{17, 12, 10, 9, 7, 4, -2, -6, -9, -13, -14}$$

3. Fill in the missing integers on the number lines below:

a) The number line shows integers from $-9$ to 4. The missing integers to reach 9 are:

$$\boxed{5, 6, 7, 8}$$

b) The number line shows integers from 0 to 4. The missing integers to reach 9 are:

$$\boxed{5, 6, 7, 8}$$

c) The number line shows integers counting by $5$s: $0, 5, 10, 15, 20, 25, 30, 35, 40$. All values are already filled in.

4. Mental Maths:

1. $8 \times 9 = ?$

$$8 \times 9 = \boxed{72}$$

2. $(3+4) \times 6 = ?$

$$(3+4) \times 6 = 7 \times 6 = \boxed{42}$$

3. $\frac{7}{7} = ?$

$$\frac{7}{7} = \boxed{1}$$

4. $\frac{0}{7} = ?$

$$\frac{0}{7} = \boxed{0}$$

5. $683 - 198 = ?$

$$683 - 198 = \boxed{485}$$

6. $13 \times 11 = ?$

$$13 \times 11 = \boxed{143}$$

7. $2642 \div 2 = ?$

$$2642 \div 2 = \boxed{1321}$$

8. $\sqrt{27} = ?$
Assuming this is $\sqrt[3]{27}$ for an integer answer:

$$\sqrt[3]{27} = \boxed{3}$$

If it is $\sqrt{27}$, then $\sqrt{27} = \sqrt{9 \times 3} = \boxed{3\sqrt{3}}$.

9. $\sqrt{16} + 9 = ?$

$$\sqrt{16} + 9 = 4 + 9 = \boxed{13}$$
