Description
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
38×32=1216
①:Multiply tens place digit by itself plus 1
(3+1)×3=12
②:Add two zeros to the end of step①
12←00=1200
③:Multiply the two one's digits together
8×2=16
④:Add the results of step ②and③
1200+16=1216

Great App
You just have to devote time do the application and do examples over and over and over again. With time your master these exercises. Your mastery will save you a lot of time.
Neat tricks
I suggest starring the ones you're most likely to need. The app taught me there are a lot more shortcuts to math than I expected.
