Description
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
• ...
▸ 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
• Subtracting the squares of two numbers differing by 2: X² − (X−2)²
• ...
▸ Multiplication:
• Any number × 5
• Two digit number × 11: ab × 11; a + b < 10

• Two 2-digit numbers with same 1s digit: ab × cb; a + c = 10
• Two 2-digit numbers with same 1s digit: ab × cb; a + c ≠ 10
▸ 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
• Any number ÷ 15
• Any number ÷ 35
▸ Percentage:

• 40% of a number
• 60% of a number
• 70% of a number
• 75% of a number
• 45% of a number

▸ Power:
• Number made up of 1s: (111..1)² ; number of digits < 10
• Number made up of 3s: (333..3)²
• Number made up of 6s: (666..6)² ; 1 < number of digits
