To calculate a partial roll of coins, enter a decimal value in the appropriate text box. For example, a value of 1.5 will equal 1Â½ rolls of coins. Do take into account the number of coins in a particular coin roll. A value of 1.5 in a dime roll text box would equal 75 total dimes, since there are 50 dimes in a roll.A value of 1.5 in a quarter roll text box would equal 60 total quarters, since there are 40 quarters in a roll.o take into account the number of coins in a particular coin roll.

The additive property of equality states that if the same amount is added to both sides of an equation, then the equality is still true. Let a, b, and c be real numbers, which consist of rational numbers (e.g., 0, -7, and 2/3) and irrational numbers (e.g., pi and the square root of 5).
Video: Additive Identity: Definition & Examples. In this lesson, you will learn the definition of the additive identity property and its meaning when applied to various kinds of numbers such as real, imaginary and complex numbers. We will also look at the application of the additive property for sets of numbers.
