What is CalculatorQueen Estimate Sums Calculator?
The Estimate Sums Calculator accepts a list of values and a chosen rounding place, rounds the addends, and then adds those rounded values. It displays the estimate beside the exact sum and quantifies their difference. This supports magnitude checks for budgets and classroom arithmetic without presenting the estimate as a reconciled total.
What problem it solves
It helps users catch missing digits, duplicated lines, and order-of-magnitude mistakes before performing or approving an exact total.
Alternatives & competitors
Mental rounding, a spreadsheet with separate rounded and exact columns, or a written classroom estimation exercise.
What is Reader Assist?
Reader Assist is a free Chrome extension designed to make web pages easier to read for people with dyslexia or ADHD, children learning to read, and anyone who finds dense text difficult. It splits long words into syllables, highlights alternating syllables or consonant-vowel pairs, and provides a reading ruler that follows the pointer to help readers keep their place.
Readers can adjust fonts, text size, letter and word spacing, ruler colours, and other settings. A reader view removes page clutter such as ads, menus, and sidebars, leaving the article in a single column. The settings follow readers across Chrome pages, and the extension can be installed on Chromebooks and other computers running Chrome. It requires no account and is free.
What problem it solves
Dense web text with long words and cluttered layouts is hard to follow for readers with dyslexia or ADHD, and for children still learning to read.
