Are there any special syntax requirements?
When you click, say, the sqrt key, the letters entered are “sqrt(“; that is, the function name is entered together with the left parentheses. You need to enter the argument, say, x+1, followed by the right parentheses, “x+1)” so it finally reads: sqrt(x+1). Entering “sqrtx+1” would produce the response: “Oops! Syntax Error.” Even if the argument is simply “x”, our syntax requires that parentheses be used: sqrt(x).
