Suppose two tasks, a and b, must use the shared variable buf_size. task a adds 2 to buf_size, and task b subtracts 1 from it. assume that such arithmetic operations are done by the three-step process of fetching the current value, performing the arithmetic, and putting the new value back. in the absence of competition synchronization, what sequences of events are possible and what values result from these operations?

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
