Algebra is the study of operations, how an object is varied from a set of numbers. Moreover, calculus is the study of change among these numbers, the chain or algorithmic patterns of change or just random sets of change is the field that calculus values which algebra can not apply or understand. However with the application of both geometry and algebra, calculus is formed. It has the direction/shape and the set of operations at its disposal.
Miss lees class collected 3 more ball because 21-18 is 3. if i collect 18 balls and my friend collects 21 balls and then we add 21+18 we get 39 and then we put 39 in 13 equal groups we have 3in each group that is why they collected 3.
21-18=3
add 21+18=39
