shortage Why can't producers increase supply if there is a sudden increase in demand? you would have to increase the price as well because otherwise it would cost too much to increase supply
Addition (often signified by the plus symbol +) is one of the four elementary, mathematical operations of arithmetic, with the others being subtraction, multiplication and division. The addition of two whole numbers is the total amount of those quantities combined. For example, in the picture on the right, there is a combination of three apples and two apples together; making a total of 5 apples.
The opposite of subtraction is addition, so I'll undo the â 3 by adding 3 to both sides, and then adding down: Then the solution is x = â2.
