-The right shift of the arithmetic is to move all the binary to the right and remove the extra right. `10` is represented as `1010` in binary, and becomes `101` after shifting one bit to the right, and converted to decimal is 5, so the right shift is seen as the following formula `a >> b => a / (2 ^ b)` by basically.
+The bitwise right shift moves all the binary digits to the right and remove the extra left digit. `10` is represented as `1010` in binary, and becomes `101` after shifting one bit to the right, and becomes 5 in decimal value, so the right shift is basically the following formula: `a >> b => a / (2 ^ b)`.
 
 Right shift is very useful, for example, you can calculate the intermediate value in the binary algorithm.
