## Examples from simple sum to scientific calculator
## Only sum and simple code
calc_sum.html
### Example shared in Facebook group HTML, CSS and JS
```
const add = (...nums) => alert(nums.reduce((a, b) => +a + +b));
add(...Array.from({length:2}, _ => prompt('Please enter a number...')));
//Although if you only see it as 1 input for the entire equation, it could be even more direct.
alert(eval(prompt('Please enter equation').replace(/[^%+-/*/(/)\d+]/g, '')));
```
