Final answer:
The provided calculations are examples of basic arithmetic operations involving negative numbers and fractions. The rules for arithmetic operations with negative numbers and positive numbers have been detailed precisely. Understanding these rules can help you efficiently solve arithmetic operations involving fractions and negative numbers.
Step-by-step explanation:
The calculations provided in the question are an example of basic arithmetic operations using negative numbers and fractions. When negative numbers are involved in arithmetic operations, they follow specific rules. When two negative numbers or two positive numbers multiply or divide, the response will have a positive sign. For example, (-3) x (1/3) = -1 or (-18 -6) x 1/2 = -12.
However, when a positive number and a negative number are involved in multiplication or division, the answer has a negative sign. For example, (-3) x 2 = -6. When you are adding or subtracting two positive numbers, the result will be positive, but if you are adding two negative numbers, the result will be negative.
Following these rules can help in solving arithmetic operations that involve fractions and negative numbers efficiently and accurately.
