Solve the following mental maths questions for the left and Thursday columns.

Here are the solutions for the mental maths questions:

Left Column:

1. Step 1: Add the numbers.

   $$160 + 45 = 205$$

   The sum is $\boxed{\text{205}}$.

2. Step 1: Subtract the numbers.

   $$88 - 11 = 77$$

   The difference is $\boxed{\text{77}}$.

3. Step 1: Multiply the numbers.

   $$3 \times 9 = 27$$

   The product is $\boxed{\text{27}}$.

4. Step 1: Add the fractions.

   $$\frac{1}{3} + \frac{1}{3} = \frac{1+1}{3} = \frac{2}{3}$$

   The sum is $\boxed{\frac{2}{3}}$.

5. Step 1: Add 2 hours to 6:30 am.

   $$6:30 \text{ am} + 2 \text{ hours} = 8:30 \text{ am}$$

   The time is $\boxed{\text{8:30 am}}$.

6. Step 1: Add the numbers.

   $$8 + 22 + 50 = 30 + 50 = 80$$

   The sum is $\boxed{\text{80}}$.

7. Step 1: Calculate $1/3$ of 3 stars.

   $$\frac{1}{3} \times 3 = 1$$

   You should shade $\boxed{\text{1 star}}$.

8. Step 1: Divide 32 by 4.

   $$4 \times 8 = 32$$

   The missing number is $\boxed{\text{8}}$.

9. Step 1: Subtract the numbers.

   $$44 - 12 = 32$$

   The difference is $\boxed{\text{32}}$.

10. Step 1: Write the number in digits. Five thousand, one hundred & ten is $\boxed{\text{5110}}$.

Thursday Column:

1. Step 1: Add the numbers.

   $$89 + 11 = 100$$

   The sum is $\boxed{\text{100}}$.

2. Step 1: Subtract the numbers.

   $$165 - 55 = 110$$

   The difference is $\boxed{\text{110}}$.

3. Step 1: Multiply the numbers.

   $$10 \times 8 = 80$$

   The product is $\boxed{\text{80}}$.

4. Step 1: Add the fractions.

   $$\frac{3}{7} + \frac{1}{7} = \frac{3+1}{7} = \frac{4}{7}$$

   The sum is $\boxed{\frac{4}{7}}$.

5. Step 1: Add 25 minutes to 4:15 pm.

   $$4:15 \text{ pm} + 25 \text{ minutes} = 4:40 \text{ pm}$$

   The time is $\boxed{\text{4:40 pm}}$.

6. Step 1: Add the numbers.

   $$80 + 30 + 60 = 110 + 60 = 170$$

   The sum is $\boxed{\text{170}}$.

7. Step 1: Calculate $2/3$ of 3 stars.

   $$\frac{2}{3} \times 3 = 2$$

   You should shade $\boxed{\text{2 stars}}$.

8. Step 1: Divide 40 by 2.

   $$2 \times 20 = 40$$

   The missing number is $\boxed{\text{20}}$.

9. Step 1: Subtract the numbers.

   $$8 - 2 = 6$$

   The difference is $\boxed{\text{6}}$.

10. Step 1: Write the number in digits. One hundred & thirty two is $\boxed{\text{132}}$.
