Fundamental to be able to solve the equations. • Includes a calculator for the calculation of logarithms to any base. • Works 100% offline • Also suitable for TEACHERS who need to build logarithmic equations as a task for students; it is possible to export LaTex code to create professional looking scripts (available as in-app purchase). • 5 levels are available: 1) Simplify (Free) 2) Expand (Free) 3) Equations - Easy (Free) 4) Equations - Medium (in app purchase) 5) Equations - Difficult (in app purchase) • Simplify: application of the rules on calculation of logarithms to compact expressions e.g.: log (5) + log (4) - log (2) = log (5 * 4/2) = log (10) • Expand: the opposite of simplify, e.g.: log (x * y/(2z)) = log (x * y) - log (2z) = log (x) + log (y) - [log (2) + log (z)] = log (x) + log (y) - log (2) - log (z) • Equations - Easy: equations that simply require the application of the definition of logarithm and application of calculation rules; are solvable in few steps and are an excellent starting point for more difficult equations. • Equations - Medium: this level presents equations that require a higher number of steps to be resolved. By mastering this level you can achieve medium/good review. • Equations - Hard: this is a level where logarithmic equations are presented that eventually leads to quadratic equations using a variable substitution, or are tricky. It also present some equations with logarithms to different bases and equations that require an excellent knowledge of the topic. By mastering this level excellent exam results are highly likely :-) ## Key features - Generates unique logarithmic equations and expressions - Provides complete step-by-step solutions - Supports simplifying and expanding logarithmic expressions - Includes a calculator for logarithms to any base - Works 100% offline - Exports LaTeX code for professional scripts ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | export LaTeX | $1.99 | one-time | | Unlocks the Medium Level | $0.99 | one-time | | Unlocks the Difficult Level | $0.99 | one-time | ## Recent user reviews (10 of 21) All indexed reviews: https://appshunter.io/ios/app/logarithms/id1138691565/reviews.md ### 1/5 — Soluzioni fantasma *2023-11-07, version 2.0* Dopo che fai la prima le altre soluzioni non appaiono,o perlomeno,appaiono nere quindi uno va alla cieca. Ha ottime potenzialità ma se rimane così è inutile ### 1/5 — Накладывание нового примера на старый *2022-04-13* При переходе на следующий пример происходит его наложение на старый, а старый не убирается **Developer response:** Thank you for the feedback, the problem has been corrected. ### 5/5 — Logarithmen *2022-02-27* Zum üben sehr gut geeignet ### 2/5 — Komma *2022-02-23* Der Rechnet erlaubt keine Kommazahlen. Sonst funktioniert der Rechner gut. ### 5/5 — Recommendation *2021-07-13, version 1.6* This app is great, I’m 15 and have never seen these before and I could understand all the easy questions in less then a hour all up. ### 1/5 — Sloppy *2019-12-02* Many exercises contain duplicates of the correct answer and it’s a gamble if you pick the correct one. The same answer listed twice...but only one of them counts as correct. ### 5/5 — 5/5 *2019-10-03* good app ### 1/5 — Che fregatura *2019-05-13, version 1.5* Per vedere le equazioni più difficili devi PAGARE!!! Sconsiglio di scaricarla. ### 1/5 — In app purchases *2018-01-23* You can only look at easy problems. If I needed help with the easy problems I would be in extra help 🙄 ### 5/5 — This app helped me so much!!!!! *2017-09-04, version 1.3* This logarithms app taught me more in 30 mins than what my teacher did in 6x70 minute lessons! Thank you so much for your amazing app!! You helped me so much! ## Frequently asked questions about Logarithms ### What are the different learning levels available in Logarithms?
