If anyone is having problems with arithmetic operations here

http://imgur.com/a/XqgAXAF

Rule is simple : 

Brackets should be solved first independent of it is multiplication or addition

Increament / decreament should be done very first , then all operations .
 
modulo / divide / multiply all lie on the same level , they have to solved from left to right . 

Addition and subtraction lie on a level below modulo / divide / multiply . If subtraction and addition both are given , solve left to right .
