Tricksy - Smart Math Tricks!

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. 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 + 2X + 2X + 2X + + 2X ( 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: X (X2) ( 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: 1111 9999 The repeated #1s 12: 1111 12 ( Locked ) The repeated #1s 13: 1111 13 ( Locked ) The repeated #1s 14: 1111 14 ( Locked ) The repeated #1s 15: 1111 15 ( Locked ) The repeated #1s 16: 1111 16 ( Locked ) The repeated #1s 17: 1111 17 ( Locked ) The repeated #1s 18: 1111 18 ( Locked ) The repeated #1s 19: 1111 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% (33%) of a number 5% of a number ( Locked ) 2.5% (2%) 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: (1111) ; number of digits < 10 Number made up of 3s: (3333) ( Locked ) Number made up of 6s: (6666) ; 1 < number of digits ( Locked ) Number made up of 9s: (9999) ; 1 < number of digits ( Locked ) Two digit number beginning with 5: (5a) ( Locked ) Two digit number ending with 5: (a5) ( Locked ) Challenge your brain to think efficiently while having fun with our smart math tricks Follow Us on Facebook: TricksyApp& Twitter: @hassantaleb90
