  • What are the arithmetic instructions?

    The arithmetic instructions define the set of operations performed by the processor Arithmetic Logic Unit (ALU).
    The arithmetic instructions are further classified into binary, decimal, logical, shift/rotate, and bit/byte manipulation instructions.

  • What are the 4 arithmetic instructions?

    The four basic arithmetic operations in Maths, for all real numbers, are:

    1Addition (Finding the Sum; '+')2Subtraction (Finding the difference; '-')3Multiplication (Finding the product; '×' )4Division (Finding the quotient; '÷')

  • What is arithmetic and logical instructions?

    ? The arithmetic instructions include addition, subtraction, multiplication, division, comparison, negation, increment, and decrement. ? The logic instructions include AND, OR, Exclusive-OR, NOT, shifts, rotates, and the logical compare (TEST).
