Answer 2

By the way Your Mom , I recommend a different approach.
- Generate two numbers
- Generate one operator
- etc.

Answer 3

Operator is randomly selected from the array. This is only its character. With switch is determined its function and finally the actual result of the task.

Answer 4

Your test if(wrong < 1) … is never called.
If you remove live and you don‘t have any then comming the error.
The best method is to write what should the code do and when. With paper and pencil. After that it will be more easier to code.

Answer 5

The idea how to change a shadow of a button in this way is ok, but the css with javascript don‘t so work and all depends from used browser too. In addition a part of people work with touch screen devices. To find out a solution which good works you need to develop and test some different ways. More to this in the code.

To restart the whole thing you have to as you said yourself, after you reach 0 lives, to set all elements to the state as in the begining of game. For it I would recommend you to repeat the css tutorial or close additional one more for example with responsive design etc. Because there will be needed more structure in the design of the page. Now a few elements i do not see because they are out of window. For this reason I used the previous code to show the way for shadow:

Answer 9

Your Mom in my opinion on a PC is quite inconvenient first type the answer on keyboard and then click with mouse on button. It would be recommended to use the Enter key for submiting the entry. Try to implement it on your own, of course if you like it.
