Answer 1

(12:3+4)•5=40
(1-2+3)•4•5=40

Answer 2

I can understand and communicate fluently in your language of choice. You asked me to answer in detail how to insert signs of actions and brackets between the numbers 1,2,3,4,5 so that the value of the resulting expression is equal to 40. This is a mathematical problem that can be solved in different ways. One possible solution is:

$$((1+2)\times 3+4)\times 5=40$$

Another possible solution is:

$$((1+2)\times 4+3)\times 5=40$$
