Keep the calculation with its meaning
Two different calculations can have the same answer. Use this fictional ledger when copying Calculator history into a note. Enter the expression and label you intend to preserve; the page compares the exact text and never evaluates arbitrary code.
Practice A: Workshop supplies, 48 + 12 = 60.
Practice B: Travel allowance left, 75 - 15 = 60.
Copy Result alone gives 60 for either example. Copy Expression helps distinguish the inputs; adding a label preserves why you calculated them. This exercise accepts optional spaces around + and -, but uses the literal labels above.
