Éducation
Gratuit · Conçue pour iPad
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
