📖 How the General Calculator Works
Brackets and precedence
(5 + 3) × 2 = 16 — brackets resolve first, then multiplication, following standard BODMAS order.
Memory keys
M+ adds the current value to memory, M− subtracts, MR recalls and MC clears — handy for keeping a running subtotal across calculations.
