Mencal is an app help you expand your ability to mentally solve math problems. All of us can do simple addition and subtraction of one or two digit numbers without a calculator.Now mencal is here to kick that ability into overdrive.Mencal provides you with lessons and simple tricks to allow you to: work with three digit numbers; fractions of different styles regardless if you are adding them or subtracting them; and finding sums with multiplication and division. Then it will test you on your grasp and knowledge of the methods you've learned. Example:- Same ten's digit,1's sum to 10 3832=1216 :Multiply tens place digit by itself plus 1 (3+1)3=12 :Add two zeros to the end of step 1200=1200 :Multiply the two one's digits together 82=16 :Add the results of step and 1200+16=1216 Quickly Square:- Square numbers made up of 1's- Square numbers made up of 3's- Square numbers in the 90's- Square numbers ten`s digit is 0- Square a number ending in 25- Square numbers made up of 6's- Square numbers made up of 9's- Square a number ending in 1- Square a number ending in 5- Square a number ending in 9- Square numbers in the 10's- Square numbers in the 40's- Square numbers in the 50's- Square numbers in the 500's- Square numbers in the 600's- Square numbers in the 700's- Square numbers in the 800's- Square numbers in the 900'sStandard:- Same ten's digit, 1's sum is 10- Same ten's digit, 1's sum isn`t 10- Same 1's digit, ten's digits sum is 10- Same 1's digit, ten's digits sum isn`t 10- two-digit number abcc (a+b=10)- abccc.....c (a+b=10)- Multiply by 11- 2-digit number if 1's digit is 1- 2-digit number if tens place digit is 1- 2-digit number 2-digit number(universal)- Multiply differing by 5- Multiply differing by 6- Multiply differing by 7- Multiply differing by 8- Multiply differing by 9- Multiply differing by 10- Multiply two numbers that in the 90s- Two-digit number like ab+ba- Three-digit number like abc+cba- Two fractions like 1/a+1/b- Two fractions like (a-1)/a + (b-1)/b- Sum of first n odd numbers- Sum of first n even numbers- Two-digit number like ab-ba- Three-digit number like abc-cba- m-n if m+n=100,1000,10000...- Two fractions like 1/a-1/b- Two fractions like c/a-c/b- Two fractions like (a-1)/a-(b-1)/b- Divide any number by 5- Divide any number by 25- Divide any number by 125- Divide any 3-figure number by 9"This app rocks!!
