Calculation Processes

  • Basic Percentage (X% of Y):
    • Purpose: Find the value of X% of Y.
    • Inputs: Percentage (X, e.g., 25%) and Value (Y, e.g., 200).
    • Formula: Result = (X / 100) × Y.
    • Example: 25% of 200 → (25 / 100) × 200 = 50.
    • Output: “25% of 200 = 50” in an animated card.
  • Find Percentage (X is what % of Y?):
    • Purpose: Determine what percentage X is of Y.
    • Inputs: Value X (e.g., 50) and Value Y (e.g., 200).
    • Formula: Result = (X / Y) × 100.
    • Example: 50 is what % of 200? → (50 / 200) × 100 = 25%.
    • Output: “50 is 25% of 200” in an animated card.
  • Original Value (X is Y% of what?):
    • Purpose: Find the original value when X is Y% of it.
    • Inputs: Value X (e.g., 50) and Percentage Y (e.g., 25%).
    • Formula: Result = (X × 100) / Y.
    • Example: 50 is 25% of what? → (50 × 100) / 25 = 200.
    • Output: “50 is 25% of 200” in an animated card.
  • Percentage Change (% Increase/Decrease):
    • Purpose: Calculate the percentage change from an original to a new value.
    • Inputs: Original Value (e.g., 200) and New Value (e.g., 250).
    • Formula:
      • Difference = New – Original.
      • Percentage Change = (Difference / |Original|) × 100.
    • Example: From 200 to 250 → Difference = 250 – 200 = 50 → (50 / 200) × 100 = 25% Increase.
    • Output: “From 200 to 250: 25% Increase, Difference: 50” (green for increase, red for decrease, gray for no change).
