Qualitative or categorical data have no logical order, and can't be translated into a numerical value. Eye colour is an example, because 'brown' is not higher or lower than 'blue'. Quantitative or numerical data are numbers, and that way they 'impose' an order. Examples are age, height, weight.
3 to the power of 5 to the power of 2-3 to the power of 0 is 9 because 3 to the power of 0 is one and 2 minus one is one and 2 to the power of one is two and 3 to the power of 2 is 9
