Speaker 1: Dear all, good morning. Now I am going to discuss some arithmetic operator in Stata like addition, subtraction, multiplication, division, exponential or logarithm, minimum and maximum. Generally we use this operator in our Stata data analysis as well as data management. Let's discuss practically. So this is our data so if we like to generate new variable income for example income is equal to just income one plus income two income. That means we have got a new variable using plus. If we savings savings is equal to income plus income two. minus expenditure this is savings using this operator we can generate new variable we will discuss detail later similarly we you can use ratio income or generate other income into thousand since this is the this value reproduced in thousand then minimum between income and expenditure maximum between income one and expenditure just for example so using this operator we can generate new variable or sometimes we need to use this operator during data analysis so we will discuss detail in the section variables generate report record thank you very much
