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.
Subtraction is a common mathematical operation that means you are taking away from some group or objects. The amount remaining after subtraction will be less. The three parts of any subtraction problem are the minuend, the part you start with; the subtrahend, the part being taken away; and the difference, the part left over.
