Final answer:
The fourth basic arithmetic operation is subtraction. In addition to using common denominators for fractions, it's essential to understand the commutative property for addition and to correctly handle whole numbers by properly placing them and using carry-over or borrowing as necessary.
Step-by-step explanation:
The fourth basic operation in arithmetic that accompanies addition, multiplication, and division is subtraction. In mathematics, these operations are fundamental for various calculations and solving problems. When working with addition and subtraction, a basic principle is to be mindful of the order and grouping of numbers, as exemplified by the commutative property (A+B = B+A) that applies to addition. As for working with whole numbers, attention should be paid to maintaining the correct number place and carrying or borrowing as needed. With fractions, it's important to consider common denominators for addition and subtraction, whereas for multiplication and division, the process involves multiplying or dividing the numerators and the denominators, keeping in mind that division by a fraction is equivalent to multiplication by its reciprocal (flipping the fraction upside-down).
