Perform daily math calculations with our free Regular Calculator. Execute standard arithmetic (+, -, ×, ÷, %), memory actions (MC, MR, M+, M-), tactile sound feedback, and session history tape tracking with 100% offline privacy.
Click on-screen numbers or type numbers using your physical keyboard.
Choose addition (+), subtraction (-), multiplication (×), division (÷), or modulo (%).
Press = to evaluate, store values in memory (M+/M-/MR/MC), or reuse previous results from history tape.
Your calculation inputs are processed entirely inside your browser using client-side JavaScript. Nothing ever travels over a network to any server — making BunchTool 100% private.
Supports full physical keyboard typing alongside web audio synthesis for tactile button click sounds.
Logs equation history with instant 'Use' and 'Copy' shortcuts, supported by MC, MR, M+, and M- memory storage registers.
A Standard Pocket Calculator handles daily arithmetic operations including addition, subtraction, multiplication, division, and percentage math.
Memory Register Functions:
\(\text{M+ (Add to Memory): } M_{\text{new}} = M_{\text{old}} + \text{Display}\)
\(\text{M- (Subtract from Memory): } M_{\text{new}} = M_{\text{old}} - \text{Display}\)
\(\text{MR (Recall Memory): } \text{Display} = M\)
\(\text{MC (Clear Memory): } M = 0\)
Use physical keys (0-9, +, -, *, /, Enter, Backspace, Escape) or touch buttons with tactile sound effects for maximum productivity.
