    the first number for C at the top left is 7 the first number for D at the top left is 1 subtract 7-1 second letters at the top C = 11 D = 0 11 - 0 first number at the bottom C = -15 D = 4 2nd number at the bottom C = 3 D = -11/12 3 - (-11/12)

    3 - (-11/12) = 3 + 11/12 you can turn 3 into a fraction 3/1 = 36/12 \(\dfrac{36}{12}+\dfrac{11}{12}=\dfrac{47}{12}=3\dfrac{11}{12}\) or you can just put 3 before 11/12 = \(3\dfrac{11}{12}\)

    just add 3 + 11/12 = \(3\dfrac{11}{12}\)

    when you subtract by a negative, it becomes positive 3 - (-11/12) = 3 + 11/12 = 3 11/12
