TinyMath is a minimalist calculator for iPhone and iPad. It calculates as you type and keeps the full expression in view.

Press "=" to save a calculation to history. • Addition, subtraction, multiplication, division and percentages. • "←" deletes the last character, "C" clears your input, and "AC" clears your history too. • Your history stays saved until you delete it. • Tap the gear for language, themes, haptics, number formatting and other settings. • Touch and hold a number in the input field to edit it without retyping the rest of the expression. The result updates automatically. EVERYDAY PERCENTAGES Percentages are based on the number to the left: 1,250 + 18% = 1,475, and 1,250 − 20% = 1,000. Work out discounts and markups, or add tax and tips, without calculating the percentage amount separately. The result updates as you type. SAVE NUMBERS FOR LATER Enter a single number and press "=" to save it in history with a "Memory" label. It stays on screen as its own entry. Tap the number to use it in your next calculation. Touch and hold “=” to save the result to memory. The expression stays in the input field so you can keep calculating. Save answers from history to memory by touching and holding the result. PARENTHESES WITHOUT EXTRA KEYS Tap an operator in the expression to put the two adjacent numbers in parentheses. Tap again to remove them: 10 − 2 − 3 becomes 10 − (2 − 3) = 11. No need to find a "(" key. COPY AND PASTE Tap any number in your history, input or result to copy it to the clipboard. If the input field is empty or ends with an operator, the number is also inserted into your current calculation. Tap "=" in a history entry to bring the full expression back into the input field. Edit or add to an earlier calculation without typing it all again. Added up a purchase but forgot shipping? Bring it back from history and add the missing cost. Hold the result to copy the expression and its answer. Tap the empty input field to paste a number or expression from another app and calculate it immediately. SOUND FAMILIAR? A calculation goes missing You add up expenses, switch to a message, then come back and have to remember which amounts you included. One lost calculation means doing the work twice. You have an answer, but can't check it The total looks wrong. Did you leave out a purchase, count an amount twice or mistype a digit? The answer alone doesn't help you find the mistake. Too many steps for a simple calculation You need to add a few amounts, reuse a number from an earlier calculation, then work out a percentage. You end up copying digits, remembering intermediate results and switching between your notes and calculator. One small change means starting over You've worked out a purchase, then remember shipping. Or you want to compare the cost for a different quantity. It's almost the same calculation, but you have to enter it all again. The interface gets in the way You just want to check a receipt or discount, but face dozens of keys with unfamiliar symbols. For everyday calculations, you want the right keys in plain sight and easy to tap. Your calculator needs other tools alongside it The calculator does the math, but amounts live in notes, answers in screenshots, and you have to remember what they mean. You want your everyday calculations in one place.

This app has a numeric keyboard. It may not always be visible. If it is not visible, pressing the input button that has the text 'Insert an Amount or ...', will cause one to appear. If you want to hide it, select the button on the left titled 'Hide KB'. The Adding Machine contains a visual tape with two columns of numbers. The left is the amount you keyed. The right column has in a '1' which is the count. The system puts in a '1' for you. As you add items, the tape grows. The last item is always followed by an empty item colored red. This color red is important because it indicates where your next entry will be placed!!! After entering a number, press the 'Save' button. If this is your first entry, two items will appear on the tape. The first one will contain the number you keyed. The second will be red with the amount showing: 0.00 and a count showing 1. This pattern will continue as you add items On the left side of the screen are 11 buttons in a column. The first six are for moving the red color - but not its contents. This allows for the correction of errors. The first two are: first - go to tape start & second to tape end (red item). The second two go up one item and down one item on the tape. The last of the group switch between amount & count - usually used to change the count from 1. There a 4 named buttons the effect the tape: Clear, Insert (an empty row where the red is, Delete(the row that a red item) and Hide KB. The keyboard has no minus sign.
