The shorthand method for adding quantities with the same amount is called multiplication. Multiplication is a mathematical operation that combines repeated addition. By multiplying a quantity by a certain number of times, you are effectively adding that quantity to itself repeatedly.

To use the shorthand method of addition, follow these steps:
1. Identify the quantity you want to add.
2. Determine the number of times you want to add the quantity.
3. Write down the quantity and multiply it by the desired number of times.

For example, let's say you want to add the quantity "5" five times:
1. Identify the quantity: 5.
2. Determine the number of times: 5.
3. Write down the multiplication: 5 x 5 = 25.

In this example, the shorthand method of adding 5 five times yields a result of 25.
