So myValue = mathFunctionAddition(2,2); Now you can go ahead and do whatever you want with myValue.
console.log is just a print statement, all languages have something similar. With console.log, you can't go ahead and do something with the value you print.

4,182 Pointsthanks,i got it,but what's the difference when i use them inside a function for example:
function square(x) { console.log(x*x); }
function square(z) { return z*z; }
see,what's the difference,because when i call the function,and i put a number inside of it,they both give me a correct answer.
