The set of numbers that is always rotational is 4. Integers.
Integers are numbers that can be positive, negative, or zero, and they include whole numbers and their negatives. Rotational symmetry is a property where a figure or object remains the same after being rotated by a certain angle around a fixed point. In the case of numbers, the rotational property means that when we rotate the number by multiples of 360 degrees, we obtain the same number.
For example, rotating the number 5 by 360 degrees will still give us the number 5.
Fractions, decimals, and positive numbers do not have rotational properties. Fractions and decimals can change significantly when rotated, and positive numbers may change depending on the angle of rotation.
