👉 The calculator math involves performing arithmetic operations on numbers, including addition, subtraction, multiplication, and division. When adding or subtracting, the calculator adds or subtracts the numbers in the specified order, starting from the leftmost digit. Multiplication and division follow the standard rules: multiplication involves multiplying each digit of one number by each digit of the other, then summing the results according to their positions, while division involves repeatedly subtracting the divisor from the dividend until the quotient is less than the divisor, then dividing by the divisor. The calculator may also handle more complex operations like exponentiation (raising a number to a power) and modulo (finding the remainder of a division), following specific rules for each operation.
