\(c`3,4.0,7+3,4.0,3-0,4=3,4.\left(0,7+0,3\right)-0,4=3,4.10-0,4=34-0,4=33,6\)

\(d`\left(1-\dfrac{1}{2}+\dfrac{3}{4}\right)-\left(\dfrac{1}{2}+1\dfrac{3}{4}-3\right)=\left(1-\dfrac{1}{2}+\dfrac{3}{4}\right)-\left(\dfrac{1}{2}+\dfrac{7}{4}-3\right)=1-\dfrac{1}{2}+\dfrac{3}{4}-\dfrac{1}{2}-\dfrac{7}{4}+3=\left(1+3\right)+\left(-\dfrac{1}{2}-\dfrac{1}{2}\right)+\left(\dfrac{3}{4}-\dfrac{7}{4}\right)=4+\left(-1\right)+\left(-1\right)=2\)
