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.
An inverse operation. Subtraction is the inverse of addition. Either of a pair of elements in a set whose result under the mathematical operation of the set is the identity element. For example, the inverse of 5 under multiplication is 1/5 , since 5 Ã 1/5 = 1, the identity element under multiplication. The inverse of 5 under addition is -5, since 5 + -5 = 0.
