As mentioned above, funds have time value, even if the amount is the same, because their value is different at different times. On the contrary, absolutely unequal funds may be of equal value at different time points under the action of time value.
These funds with different maturities and different amounts but "equivalent" are called equivalence, also called equivalence. Capital equivalence and compound interest are calculated in the same form.
Many equivalent formulas are verified by truth table method, and some of them are very important and are an important part of Boolean algebra. The important equivalent formula is one of the keys to learn mathematical logic well.
