Use the scientific calculator

Type whole sums, use sin, cos and tan in degrees or radians, powers, roots, logs and nCr, and reuse answers from the tape.

The calculator works like a school scientific calculator: you type the whole sum, see it, then press equals.

Step 1: Go to ganzaa.org/tools/calculator, or choose Calculator from the wrench.
Step 2: Type your sum with the keys or your keyboard, for example 2×(3+4)−1. The answer shows in grey as you type.
Step 3: Press = or Enter to finish. The sum and its answer are added to the Tape.
Step 4: Angles are in degrees. Press DEG to switch to radians; the key then shows RAD. Your choice is remembered on this device.
Step 5: Press 2nd to get the second functions: sin⁻¹, cos⁻¹, tan⁻¹, eˣ, 10ˣ, ∛, x³, ʸ√x and nPr.
Step 6: After =, press an operator such as + to carry on from the answer (Ans). Tap any line on the tape to put its answer into your sum.
Step 7: Press AC to clear everything, or the delete key to remove the last thing you typed.
