Calculator 2024 vs Smart Calculator+

Here come the general/special purpose equation/function calculator! Students, scientists, accountants, merchants, anyone can easily use it for a instant result. Usage: -equation string, e.g. 1+2x3-4÷5.0-.2+1+2^5 = 39 -VAT % calculation, e.g. 7 % x 56000 = 3,920 -Auto Floating point operation, e.g. 11÷2 = 5.5 11.0÷2 = 5.5 11÷2.0 = 5.5 -compound operators and precedence +, -, x, ÷, ^, e.g. 1+2x3÷4-5 = -2.5 1+2x3÷4.0-5 = -2.5 2^10 = 1024 -use parenthesis ( ) as highest operator precedence. e.g. (3+6)x2-3÷2 = 16.5 -always use parenthesis to prevent ambiguity, e.g. √9+2 means √11, to get √9 plus 2, equation must be (√9)+2, result: (√9)+2 = 5 -perform x^y, e.g.2^16 = 65,536 -perform square root, e.g. tap √ , tap 6 2 5, tap = , result: √625 = 25 -compute %, e.g. to compute 5% of 300. Tap 5, tap %, tap x, tap 3 0 0, tap =, result: 0.05x300 = 15 -compute logarithm base 10, e.g. to compute log1000, Tap log, tap 1 000, tap =, result: log1000 = 3 -equation log100+10 means log110, to compute log100 plus 10, equation must be (log100)+10, result: (log100)+10 = 12 -compute natural logarithm base e, e.g. ln2, Tap ln, tap 2, tap =, result: ln2 = 0.693147 -compute factorial, e.g. 5!, Tap 5, tap !, result: 5! = 120 -compute inverse of x or 1/x, e.g. 1/25, Tap 25, tap 1/x, result: 1/25 = 0.04 -compute area of a circle with radius 5, e.g. Tap 2, tap x, tap Pi, tap x, tap 5, tap =, result: 2xPix5 = 31.4159 -Continuous computation, e.g. to compute 7.5% of 800 then add by 1000. Tap 7.5, tap %, tap x, tap 800, tap +, tap 1 000, tap =, result: 0.075x800+1000 = 1060 -Tap share button to share the result of the computation to other apps. -Tap M+ to add result in memory,  -Tap M- to subtract result in memory,  -Tap MR to recall result from memory. -Tap MC to clear result from memory. -Tap hist button to to view and select the previous calculation history. -long press equation or result label to copy/paste equation and/or result to/from other app, e.g. 17.0+2x3-4x5÷6+7-8x9÷5+6x7-5 = 49.266667 -Tap speaker On/Off button to toggle button click sound. Note: -Operators (, ), +, -, x, ÷, and ^ can combine into a long equation string. e.g. 17+2x3^2-4x5÷6.0+(7-8)x9÷5.0+6x7-5 = 66.866667 -Computation follows operator precedence, e.g. 1+2x3-2^3+1 = 0 2x(3+4)÷3.0+5 = 9.666667 -Operators !, % and 1/x can only be used in a single operation or first operator in mixed operation. e.g. 5!, 6%, but not 2 + 5!, not 20 + 5%. -but can use as first operator. e.g. 5! + 2, or 5% + 20. - Mod operator can not be mixed with other operators, to compute 34 mod 5. Tap 3, Tap 4, tap Mod, tap 5, tap =, result: 34 Mod 5 = 4 - nCr operator can not be mixed with other operators, to compute 5 nCr 2. tap 5, tap nCr, tap 2, tap =, result: 5 nCr 2 = 10, note that, n>=r>=0. Invalid equation: 2√9 must change to 2x√9 2log100 must change to 2xlog100 2Pi5 must change to 2xPix5 In equation, multiplication must always use x operator.

We REMOVED "EQUAL TO" button and replaced it with "SAVE" which saves your calculations shows you all the entries in history log. Excellent for double checking for errors. It is Fast, Simple, Effortless!! (For iPhone and iPad) Real-Time Auto Calculation Results are calculated automatically as you type. Perfect for continuous transactions and fast daily calculations. Left-to-Right Calculation Calculates in natural input order, making it simple and practical for everyday business use. NO EQUAL TO button = now REMOVED With smart and intuitive programming we REMOVED the "=" [EQUAL TO] key because it calculates as you type and shows the result immediately. But we replaced it with SAVE button/function. Click on SAVE and RETRIEVE the calculation history by clicking on the log on left top (tape history). Memory Functions (M+, M-, MR, MC) Store, add, subtract, and recall values easily during calculations. Calculator Tape = Full History Log Track all your previous entries. You can go back and see what you typed and or missed. Calculator Tape = Log Features You can EDIT, COPY, EMAIL, SHARE, DELETE & CANCEL and reuse calculations anytime WITHOUT RECALCULATING and re-entering.
