Which of the following is not an arithmetic operation?
a. a *= 20;
b. a /= 30;
c. a %= 40;
d. a ! = 50;

D. a !=50 is a condition and therefore it is not an arithmetic operation.

Let me know if you have any questions.

b. related objects

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
