Answer 3

Let's break down the expression step by step:

1. $28 \times 2 \frac{1}{2}$ (28 times 2 and a half): $28 \times 2 \frac{1}{2} = 28 \times 2 + 28 \times \frac{1}{2} = 56 + 14 = 70$

2. $2 \frac{1}{2} \times 18$ (2 and a half times 18): $2 \frac{1}{2} \times 18 = 2 \times 18 + \frac{1}{2} \times 18 = 36 + 9 = 45$

3. $0.25 \times 31 \times 4$ (0.25 times 31 times 4): $0.25 \times 31 \times 4 = 7.75 \times 4 = 31$

Now, putting it all together:

$70 - 45 + 31 = 56$

So, the final result of the expression is 56.
