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 in mathematics means you are taking something away from a group or number of things. When you subtract, what is left in the group becomes less. An example of a subtraction problem is the following: 5 - 3 = 2. Notice that there are three parts to the subtraction problem shown. The part you start with is called the minuend.
