Frequently asked questions
Does this calculator respect order of operations?
Yes - it uses a proper expression parser that follows standard mathematical order of operations (parentheses, exponents, multiplication/division, then addition/subtraction), not a naive left-to-right evaluation.
Can I switch between degrees and radians for trig functions?
Yes - use the DEG/RAD toggle before entering sin/cos/tan calculations to get the mode you need.
Does it have memory functions?
Yes - M+, M-, MR, and MC work the same way as a physical scientific calculator, and there's a calculation history panel so you can review previous results.
