About this calculator
A calculator that respects order of operations: multiplication and division bind tighter than addition and subtraction, so 2 + 3 × 4 is 14, not 20. Parentheses override that ordering when you need a different grouping.

Frequently asked questions
Does it follow order of operations?+
Yes — it evaluates the full expression with correct operator precedence (× and ÷ before + and −), and supports parentheses.
How do the memory keys work?+
M+ adds the current value to memory, M− subtracts it, MR recalls it, and MC clears it.
