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

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

I like the idea of ​​training the mind, that the calculation is not that simple and it takes a little eye of intuition. But if you need to train your mind is fine. I would have also included the time for those who want it would be really compelling if you can then challenge your friends with a little challenge. Happy game :)))))
