How This Calculator Works
Type an expression using the keypad — it supports standard order of operations, so 3 + 4 × 2 correctly evaluates to 11, and parentheses group operations exactly like on paper. If you forget to close a parenthesis, it's completed automatically when you press =.
2nd switches sin/cos/tan to their inverse functions (sin⁻¹/cos⁻¹/tan⁻¹) and switches ln/log to eˣ/10ˣ. Deg/Rad controls whether trig functions use degrees or radians. x², √, 1/x and n! apply to the number (or result) you've just entered.
The memory keys work like a physical calculator: M+/M− add or subtract your current result to a stored value, MR recalls it into your entry, and MC clears it.
Frequently Asked Questions
Yes. Unlike a simple four-function calculator, this scientific calculator correctly applies standard order of operations (PEMDAS), so 3 + 4 × 2 evaluates to 11, not 14. Parentheses are also fully supported and auto-completed if you forget to close them.
Press the Deg/Rad button above the keypad to toggle the angle mode. It affects sin, cos, tan and their inverse functions.
It switches sin, cos and tan to their inverse functions (sin⁻¹, cos⁻¹, tan⁻¹), and switches ln and log to their exponential counterparts (eˣ and 10ˣ).
MC clears the stored memory value. MR inserts the stored value into your current entry. M+ adds your current result to memory, and M− subtracts it.
