add
~~~


.. function:: add(evm: ethereum.tangerine_whistle.vm.Evm) -> None
   :noindexentry:

   Adds the top two elements of the stack together, and pushes the result back
   on the stack.

   :param evm: The current EVM frame.

   :language: python
   :pyobject: add

sub
~~~


.. function:: sub(evm: ethereum.tangerine_whistle.vm.Evm) -> None
   :noindexentry:

   Subtracts the top two elements of the stack, and pushes the result back
   on the stack.

   :param evm: The current EVM frame.




.. undocinclude:: /../src/ethereum/tangerine_whistle/vm/instructions/arithmetic.py
   :language: python
   :pyobject: sub

mul
~~~


.. function:: mul(evm: ethereum.tangerine_whistle.vm.Evm) -> None
   :noindexentry:

   Multiply the top two elements of the stack, and pushes the result back
   on the stack.

   :param evm: The current EVM frame.

mod
~~~


.. function:: mod(evm: ethereum.tangerine_whistle.vm.Evm) -> None
   :noindexentry:

   Modulo remainder of the top two elements of the stack. Pushes the result
   back on the stack.

   :param evm: The current EVM frame.
