Example-1 Suppose ( a=5.b=4.c=2 ,i=2.j=1) Execute the following expressions in order of precedence: 1- a + b + c/ 12 2- 2-(a+b+c)/12 3- a +b/c-1*j+a-2 4- 4- a*b-c/1+j + a^b+c^3?a* j^b-1/c*j + 20 5- j/(I+c)?j/I+c? (a* (b+1)* c)^2? (j+I* (b/c-a^2)+i 6- (I+j)/a? I+j/a?(j* (a^2-10))/2 7- i+j^2-3* a? ((I+j)/3* a )^2/2
