Tricksy is a universal app that allows you to solve many math operations in a simple way, by applying untraditional techniques. This app includes more than 60 lessons classified into these domains: Addition, subtraction, multiplication, division, percentage and power. These lessons are presented in levels, arranged from the easiest lesson to the most difficult one. Each of these lessons is explained in a simple and clear way; using steps supported by examples. Besides the lessons, tricksy includes some useful tools for calculation, in which students can benefit, and may apply them during their school domain. ~The included tricks are: ▸ Addition: • Adding two-digit numbers like ab + ba • Adding 2 fractions like 1/a + 1/b • Adding a sequence of odd numbers beginning by 1: 1 + 3 + 5 + … + 2n-1 • Adding a sequence of even numbers beginning by 2: 2 + 4 + 6 + … + 2n • Adding a sequence from 1 to any number and back to 1 again: 1 + 2 + 3 +…+ X +…+ 3 + 2 +1 • Adding a sequence of doubles: X + 2⋅X + 2²⋅X + 2³⋅X + ... + 2ⁿ⋅X ( Locked ) • ... ▸ Subtraction: • Subtracting two-digit numbers like ab − ba • Subtracting 2 fractions like 1/a − 1/b • Subtracting 2 fractions like c/a − c/b • Subtracting 2 fractions like (a − 1)/a − (b − 1)/b • Subtracting three-digit numbers like abc − cba ( Locked ) • Subtracting the squares of two numbers differing by 2: X² − (X−2)² ( Locked ) • ... ▸ Multiplication: • Any number × 5 • Two digit number × 11: ab × 11; a + b < 10 • Two digit number × 11: ab × 11; a + b ≥ 10 • Any number × 9 • The repeated #1s × the repeated #9s having the same # of digits: 111..1 × 999..9 • The repeated #1s × 12: 111..1 × 12 ( Locked ) • The repeated #1s × 13: 111..1 × 13 ( Locked ) • The repeated #1s × 14: 111..1 × 14 ( Locked ) • The repeated #1s × 15: 111..1 × 15 ( Locked ) • The repeated #1s × 16: 111..1 × 16 ( Locked ) • The repeated #1s × 17: 111..1 × 17 ( Locked ) • The repeated #1s × 18: 111..1 × 18 ( Locked ) • The repeated #1s × 19: 111..1 × 19 ( Locked ) • Consecutive decade ending in 5: a5 × b5; b = a + 1 ( Locked ) • Two 2-digit numbers with same 10s digit: ab × ac; b + c = 10 ( Locked ) • Two 2-digit numbers with same 10s digit: ab × ac; b + c ≠ 10 ( Locked ) • Two 2-digit numbers with same 1s digit: ab × cb; a + c = 10 ( Locked ) • Two 2-digit numbers with same 1s digit: ab × cb; a + c ≠ 10 ( Locked ) ▸ Division: • Any number ÷ 5 • Any number ÷ 50 • Any number ÷ 25 • Any number ÷ 250 • Any number ÷ 125 • Repeating 3-digit number ÷ 37: aaa ÷ 37 • Any number ÷ 40 ( Locked ) • Any number ÷ 15 ( Locked ) • Any number ÷ 35 ( Locked ) ▸ Percentage: • 50% of a number • 25% of a number • 20% of a number • 33.33...% (33⅓%) of a number • 5% of a number ( Locked ) • 2.5% (2½%) of a number ( Locked ) • 40% of a number ( Locked ) • 60% of a number ( Locked ) • 70% of a number ( Locked ) • 75% of a number ( Locked ) • 45% of a number ( Locked ) • 15% of a number ( Locked ) • ... ▸ Power: • Number made up of 1s: (111..1)² ; number of digits < 10 • Number made up of 3s: (333..3)² ( Locked ) • Number made up of 6s: (666..6)² ; 1 < number of digits ( Locked ) • Number made up of 9s: (999..9)² ; 1 < number of digits ( Locked ) • Two digit number beginning with 5: (5a)² ( Locked ) • Two digit number ending with 5: (a5)² ( Locked ) Challenge your brain to think efficiently while having fun with our smart math tricks ! -------------------------------------------- Follow Us on Facebook: TricksyApp & Twitter: @hassantaleb90

Abacus Trainer 2 is a question generator made in accordance with the skills acquired in rapid calculations. It provides a whole range of options that can be flexibly selected to fit the drilling needs. The immense pool and combination of questions enhance the learning interest. Exercises can be set on any kind of vedic maths calculations including multiplicative pithy formula. Flexible answer input can be entered either by using abacus or numeric keys. Two modes are designed to fit different learning needs. Practice mode supports endless number of questions with no time limit, with the purpose of accuracy. Challenge mode requires answers to all the questions within the specific time limit, encouraging to boost speed as well as accuracy. No matter practice or challenge modes, the performance, score and every detail will be recorded in report, which is useful for learning progress monitoring. The report records assist you to find out the strength and weakness, a customized approach in abacus training can be derived as a result. Apart from doing the exercises directly on iPad in a timed way, export both the quiz paper and the answer paper in pdf format to aid offline exercises. All questions are generated randomly to ensure no quiz paper will be identical. Print and email functions are also provided for your convenience. Interested in Abacus Tutorials?
