Commerce Setup -> Order System -> Shopping Cart. Uncheck (if checked) the 'Do not display the the "Show me my shopping cart" check box', then check 'Default for the "Show me my shopping cart" checkbox' and Save Changes.
Note that this new default will only affect new shopping carts, so if you have items in your cart currently, Empty Cart and then re-add items to your cart to see the new default behavior.
