    Calculation $\bullet$
    D(x3+2x2+x+1) Write a step of calculation.
    For example: "2x+1=5x-2"
    = Write here the relation between steps. For example: "=" or "⇔"
    use the sum rule to separate the terms Here you can write your explanation.
    For example: "Multiply both sides by 3"
    Add a nested task
    Dx3+D2x2+Dx+D1 Write a step of calculation.
    For example: "2x+1=5x-2"
    = Write here the relation between steps. For example: "=" or "⇔"
    calculate the derivative of each term Here you can write your explanation.
    For example: "Multiply both sides by 3"
