説明
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
