     - `11` is represented in bits by `1011` which when right shifted by 1 bit gives `101`which is the decimal `5`.
 
 - `&` (bit-wise AND)
-    - Bit-wise AND of the numbers: if both bits are `1`, the result is `1`. Else it's `0`.
+    - Bit-wise AND of the numbers: if both bits are `1`, the result is `1`. Otherwise, it's `0`.
     - `5 & 3` gives `1` (`0101 & 0011` gives `0001`)
     
 - `|` (bit-wise OR)
-    - Bitwise OR of the numbers: if both bits are `0`, the result is `0`. Else it's `1`. 
+    - Bitwise OR of the numbers: if both bits are `0`, the result is `0`. Otherwise, it's `1`. 
     - `5 | 3` gives `7` (`0101 | 0011` gives `0111`)
     
 - `^` (bit-wise XOR) 
-    - Bitwise XOR of the numbers: if both bits (`1 or 0`) are the same, the result is `0`. Else it's `1`.
+    - Bitwise XOR of the numbers: if both bits (`1 or 0`) are the same, the result is `0`. Otherwise, it's `1`.
     - `5 ^ 3` gives `6` (`O101 ^ 0011` gives `0110`)
 
 - `~` (bit-wise invert)
