Question
t/3 + t-5/3

Answer
Hi Corey,

(t/3) + t - (5/3)

the common denominator is 3 in the first and third term.  Multiply the second term by 3/3 to get the denominator of 3 in that term.  Note that we can do this because 3/3 = 1, so we are not changing the value because anything multiplied by 1 is itself.

(t/3) + (3t/3) - (5/3)

since we have the same denominator in all three terms, we can add the numerators and put them over a single denominator.

(t + 3t - 5)/3
we can add t and 3t

(4t - 5)/3

That is the answer.  Let me know if you have any questions.
