That's right. You should enclose with parenthesis when writing a computer program - because it won't understand you are trying to divide by t. But if you write a normal dash with a horizontal big line  and put the t underneath- then it should not be necessary. In this case it actually will not matter what you multiply by first and divide by first. Just make sure the t is in division.
