How to use this calculator
Keyboard shortcuts

Memory buttons (M+, MR, MC)
- M+ — add current display to memory
- MR — recall the stored memory value
- MC — clear memory to zero
Memory is useful for storing an intermediate result (e.g., a denominator or running total) while you compute a second value, then recalling it for a final calculation.
When should you use the calculator on the GRE?
The on-screen calculator is available only on Quantitative Reasoning sections. Use it for arithmetic-heavy computations (large multiplications, percentages, square roots) rather than algebraic or reasoning steps. For most GRE Quant questions, mental math or estimation is faster than the calculator — reserve it for the final numeric step when precision matters.
