Equation & Expression Solver vs Idioms Park

Equation & Expression Solver helps middle and high school students solve and simplify algebra — and actually understand it, by showing every step along the way. Type an equation or expression on the built-in math keypad — variables, fractions, exponents, and parentheses included — then tap Solve or Simplify. You get the answer AND the worked steps that lead to it, the way a teacher would write them on the board. What it does • Solves linear and simple polynomial equations • Gives square-root answers in exact, simplified form — x² = 20 is ±2√5 — with the decimal approximation on the line below, so you get the form to hand in and the number to sanity-check it against • Simplifies expressions, combines like terms, and distributes • Adds, subtracts, multiplies, and divides fractions — even with variables • Factors differences of squares, sums and differences of cubes, and trinomials • Shows the work, step by step, with a clear caption for each move Built for learning • A custom keypad made for math — no fighting the keyboard • Clean, readable notation for fractions, exponents, and roots • Honest answers: when a problem is beyond it, it says so rather than guessing No accounts, no ads, no data collection. Just you and the math.

Some English you can't look up. "Break the ice." "Hit the nail on the head." "Once in a blue moon." You know every word. The sentence still means something else. That gap is what keeps people who are fluent on paper sounding foreign in the room. It's also the one thing textbooks leave out. IdiomsPark closes it. LEARN THEM THE WAY THEY'RE ACTUALLY USED Every idiom comes with a plain-English meaning, a sentence you'd really hear, and a translation in your own language. Tap to hear it spoken aloud. No dictionary tone, no dusty phrases nobody has said since 1950. STOP FORGETTING THEM Most apps show you something and hope it sticks. IdiomsPark works out when you're about to lose an idiom and puts it in front of you the moment before you do. Answer confidently and it steps back for months. Hesitate, and it's there again tomorrow. You never plan a revision session — the schedule builds itself around what you personally find hard. A FEW MINUTES, NOT AN EVENING Learn a handful at a time, grouped by where you'd actually use them: work, money, feelings, relationships, time. Then test yourself on what you've studied — never on what you haven't. Idioms that keep catching you out stay on your list until they don't. ONE IDIOM A DAY, WITHOUT OPENING THE APP Put the widget on your Home Screen and a new one is waiting each morning. Save it with a single tap and come back to it when you have a minute. YOURS, AND ONLY YOURS No ads. No subscription. No account. Nothing tracked, nothing uploaded, nothing sold. It works on a plane, on the subway, in a basement — because it was never asking the internet for anything. Available in English, Simplified Chinese, Traditional Chinese, Japanese, Korean, German, Spanish and Italian.
