Please help

Can somebody please break this down for me, what the mathematical process is of the following var x = “2*2” var y= 4 var z = eval(x+y) alert(z)

// Because you make the 1st variable with a string and he can not make the operation. But if you use int, JavaScript can make the operation as a calculator.

hi Luke Sandford ok so x is a string value then y is an int value z evaluates to a string because it is the first value so the output is 2*24 i hope this helps
