What are the values of the following expressions? In each line, assume that
double x = 2.5;
double y = -1.5;
int m = 18;
int n = 4;
a. x + n * y - (x + n) * y
b. m / n + m % n
c. 5 * x - n / 5
d. 1 - (1 - (1 - (1 - (1 - n))))
e. Math.sqrt(Math.sqrt(n))
a.) 2.5+4*-1.5-(2.5+4)*-1.5=2.5-6-(6.5)*-1.5=2.5-6+9.75=2.5+3.75=6.25
b.) 18/4 + 18%4= 4 + 2=6
(In programming language “/“ symbol will produce the closest number to the answer and round down in this case 4*5 = 20, take the 5 and round down to 4 which is closest to 18/4. Furthermore in programing language the “%” symbol will only get the remainder of 18/4=2.)
c.) 5*2.5-4/5=12.5-0=12.5
d.) 1-(1-(1-(1-(1-4))))= 1-(1-(1-(1-(-3))))= 1-(1-(1-(4)))= 1-(1-(-3))= 1-(4)=-3
e.) Math.sqrt(Math.sqrt(4))=
