Detailed explanation-1: -Processors have a circuit called the arithmetic and logic unit that carries out calculations and comparisons. The arithmetic most CPUs perform is basic multiplication, addition, division and subtraction; complex math such as statistical functions are combinations of many simple operations performed at high speed.
Detailed explanation-2: -The actual mathematical operation for each instruction is performed by a combinational logic circuit within the CPU’s processor known as the arithmetic–logic unit or ALU. In general, a CPU executes an instruction by fetching it from memory, using its ALU to perform an operation, and then storing the result to memory.
Detailed explanation-3: -The arithmetic logic unit (ALU) performs mathematical calculations; it is the part that computes.
Detailed explanation-4: -A calculator is a device used for mathematical calculations and has a small keyboard and display screen that shows the results.
