 ### Exponentiation **
 
-The exponentiation operator `a ** b` multiplies `a` by itself `b` times.
+The exponentiation operator `a ** b` raises `a` to the power of `b`.
+
+In school maths, we write that as a<sup>b</sup>.
 
 For instance:
 
 ```js run
-alert( 2 ** 2 ); // 4  (2 multiplied by itself 2 times)
-alert( 2 ** 3 ); // 8  (2 * 2 * 2, 3 times)
-alert( 2 ** 4 ); // 16 (2 * 2 * 2 * 2, 4 times)
+alert( 2 ** 2 ); // 2² = 4  
+alert( 2 ** 3 ); // 2³ = 8 
+alert( 2 ** 4 ); // 2⁴ = 16
 ```
 
-Mathematically, the exponentiation is defined for non-integer numbers as well. For example, a square root is an exponentiation by `1/2`:
+Just like in maths, the exponentiation operator is defined for non-integer numbers as well. 
+
+For example, a square root is an exponentiation by ½:
 
 ```js run
 alert( 4 ** (1/2) ); // 2 (power of 1/2 is the same as a square root)
