1//Math in JS is similar and different to the one in real life
2//Like: "+", "-" signs are the same. But "X" and "÷" are replaced with "*" and "/" respectivly
3//You can do math both with variables and normal numbers
4________________________________________________________________________________
5								Normal Number Examples
6                                
74+4 = 8;
84-4 = 0;
94*4 = 16;
104/4 = 1;
11________________________________________________________________________________
12								Variable Examples
13                                
14num1 = 0;
15num2 = 0;
16ans = 0;
17
18num1 = 4;
19num2 = 64
20
21num1 + num2 = 68
22num1 - num2 = 60
23num1 * num2 = 24
24num1 / num2 = 256;
25
26num1 + num2 = ans;
27num1 - num2 = ans;
28num1 * num2 = ans;
29num1 / num2 = ans;
30________________________________________________________________________________
31Now, you can use the document.getElementByID("").innerHTML = ans; to set the answer

1The top-level element in MathML is <math>. Every valid MathML instance must be wrapped in <math> tags. In addition you must not nest a second <math> element in another, but you can have an arbitrary number of other child elements in it.
