Mysterious syntax errors... help?

[friendlymegalomaniac]

Trying to code, but keep on getting syntax errors. It says 'answer =' and 'return output
are improper. I am using python 3

def exponential():
	base = int(input('Your base number:'))
	exponent = int(input('Your exponential'))
	answerexp = base ** exponent
	output = '%s to the power of %s equals %s'%(str(base),str(exponent),str(answer))
	return output
def minus():
	num1 = int(input('Your 1st number:                  '))
	num2 = int(input('Your 2nd number:                  '))
	answer = num1 - num2
	output = "%s minus %s is equal to %s"%(str(num1),str(num2),str(ans))
	return output
def add():
	num1 = int(input('Your 1st number:                  '))
	num2 = int(input('Your 2nd number:                  '))
	answer = num1 + num2
	output = "%s plus %s is equal to %s" %(str(n1),str(n2),str(ans))
	return output
def sqroot():
	number = int(input('Your number:                        '))
	output = number ** (1. / 2)
	return output
def root():
	exponent = int(input('Your number to root:               '))
	root = int(input('Your root to be used:             '))
	answer = exponent ** (1. / root)
	output = '%s with the root of %s is %s'%(str(exponent),str(root),str(answer)
	return output

	
	
def func():	
	func = input("What do you want to do?            ").lower()
	if func == 'divide':
		answer = divide()
		print(answer)
		func()
	elif func == 'multiply' or 'times':
		answer = multiply()
		print(answer)
		func()
	elif func == ('power' or 'exponent') or ('exponential' or 'exponents'):
		answer = exponential()
		print(answer)
		func()
	elif func == 'minus' or 'subtract':
		answer = minus()
		print(answer)
		func()
	elif func == 'root':
		answer = root()
		print(answer)
		func

On line 27 you're missing a close-parenthesis.

I have fixed that, but the errors persist.

When I take your code and make that one change, I don't get a syntax error. What's the exact, latest code you're using, along with its full error message? If you're using an IDE, it'd probably be worth getting the error message by using a terminal / console.
