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.
Any operation â for which aâb = bâa for all values of a and b. Addition and multiplication are both commutative. Subtraction, division, and composition of functions are not. For example, 5 + 6 = 6 + 5 but 5 â 6 â  6 â 5. More: Commutativity isn't just a property of an operation alone. It's actually a property of an operation over a particular set. For example, when we say addition is commutative over the set of real numbers, we mean that a + b = b + a for all real numbers a and b. Subtraction is not commutative over real numbers since we can't say that a â b = b â a for all real numbers a and b. Even though a â b = b â a whenever a and b are the same, that still doesn't make subtraction commutative over the set of all real numbers.
