Description of One By One

One By One is a math study game for middle and high school students. Problems are randomly generated to receive different problems! Step your mental math game up to the next level! Additionally you can refine practice problems by choosing specific one in the "One By One Battles" menu. FEATURES: UNICODE/ASCII Art Style. This app was designed to mimic the "nostalgic" or retro feeling on calculators with ASCII art and simple design. The background music continues this feeling with the satisfying key clicks. A leveling system. Go from level 1 to 99 by solving problems each step of the way! Every ten levels you unlock a brand new set of mathematical questions to help study. ARITHMETIC. Whether you need to practice what 1+1= or what (4+3)²/(4-2)³= we got you. ALGEBRA. As you enter into high school most students struggle with algebra, help yourself out and solve some fancy algebra equations like 3x+4=5. As you progress through the levels you can grind your way up to √(x+4)*2=6 TRIGONOMETRY. I think we can all admit that the unit circle can be tricky. Through the exp system, you can work at your own pace and master sin(0) before being overwhelmed by cot⁻¹(-1). If you are already a master of sin and cos you can blow past those problems and gain some easy in-game money! For those of you who struggle with trigonometry there's even a unit circle to help! CALCULUS DERIVATIVES. Derivatives? That's right finally you can practice the derivative rules in any setting. The problems are perfectly tuned to be anywhere from easy mental math to slight difficult mental math. You can practice the power rule or try to figure out what the derivative of ln(2x+3) is. LEADERBOARDS & ACHIEVEMENTS: Have a competitive personality? Well, there are now 5 new leaderboards. Each game mode has its own leaderboard and the final one is based on your balance. There is also a hidden achievement, hint you better get solving! UPGRADES: You have a chance of encountering a "Golden Problem", solve correctly and you'll receive a math artifact that can be equipped to enhance your experience. There are 25 artifacts with 9 unique upgrades that can be used to strategize your problem-solving career! AI BATTLES: If you are feeling competitive or want to practice a certain type of problem you can use the One By One Battles mode to get the perfect training. Additionally, you get rewarded for choosing faster AI and winning! The perfect study tool. No matter what level of math you are this app is perfect for refining your mental math in a visually pleasing retro Unicode calculator style. You can transfer from arithmetic to calculus in seconds. What are you waiting for? Download the app and solve math faster than your teacher!

Reviews of One By One

  • Incorrect Calculation?

    tan(5pi/6) is wrong. I’m unsure what the answer has been programmed to be but whatever it is, it’s not accurate. Other than that, great game.
  • Almost Perfect

    This is a wonderful app and great opportunity for practicing mental math. And this is why I care enough to make a bug report.

    Please fix calculus. Some of the answers require infinity, and this is not allowed in the answers. For example, I recently got the question: Given h(x) = 8/x find h’(0). The answer is -∞ as this is the limit from the left and right hand sides, but this is impossible to enter with the ‘Differential Departments’ keyboard.

    One possible stopgap solution would be to make the correct answers available if you pay for a skip (with in-game currency), this way we users can figure out what the game wants in such strange situations. Alternatively, you could take away the questions generating these issues, possibly by plugging all differentiation questions into the Wolfram engine to check the outcomes and then deleting the ones that don’t match. Of course, this won’t work if the questions are auto generated and not drawn from a bank —unless you run all possible questions (which would probably take a long time).
  • Love it, want more!

    I’ve been having a lot of fun with the app! The derivative and trig section is great practice to knock the rust off my calc now that I’m back in complex analysis. I’d love to see more sections added such as integrals, combinatorics, some kind of series stuff, maybe even some set theory unions and intersections type stuff! I would pay for some extra packs of the sorts! Thanks!

    Developer Response

    Wow thank you for the amazing review! It is awesome to see that the app is appealing even for such a high level of math! Those modes would be great to see in the app one day.
