Answer:

3 select inputs are required to select a specific input between 5 inputs.

Explanation:

Multiplexer is used to select the inputs from different inputs to a single output. There are many types of multiplexers for different number of inputs selection. 1. 2x1 is the type of multiplexer where 2 inputs and 1 output. This is used to select between these inputs. There is one more pin to select the input between these two inputs that is called <em>select </em>input.

2. Another type is 4x1 multiplexer. There are 4 inputs and one output. In this type of multiplexer 2 select pins are used for selection of input bits between these 4 inputs.

For more than 4 inputs and less than 8 inputs, 8x1 multiplexer is used. this multiplexer uses three inputs for selection purpose.

a_sh-v [17]

Answer:

previousAddition instance variable

Explanation:

In order to accomplish this you would need to add a previousAddition instance variable. In this variable you would need to save the amount that was added at the end of the process. Therefore, if a mistake were to occur you can simply call the previousAddition variable which would have that amount and subtract it from the total. This would quickly reverse the mistake, and can be easily called from the undo() method.
