The balance of trade is nothing but the country's exports minus the country's imports.
Exports means, what you produce in the country and sell it to other countries, whereas imports means what you get or buy from the other countries.
When you export more than you import, you have trade surplus .In that case the income from exports are more than the money spent. So you have a trade surplus.
When you import then you have a trade deficit or your income is low. Most of the countries want a trade surplus.
