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 youve learned.
• Example:
Same tens digit,1s 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 ones digits together
8×2=16
④:Add the results of step ②and③
1200+16=1216

Neat tricks
I suggest starring the ones youre most likely to need. The app taught me there are a lot more shortcuts to math than I expected.
Trop toooop
J étais à l aise avec les chiffres à l école mais là avec ces techniques bien expliquées pour le calcul mental ( ça fait bosser l anglais au passage ;) Ça aurai été encore mieux Je suis ravi d avoir eu la chance de tomber dessus pdt que c etait gratuit je ne l aurai jamais prise sinon mais pour un jeune qui galère un peu en calcul ça peu vite le faire se sentir à l aise et a ce moment là investissement rentable Véridique merci pour cette appli PS d habitude je perd pas mon temps à rédiger un avis bon ou mauvais dailleurs mais là j ai vraiment été agréablement surpris Et ça fait jeu aussi ;)
Bonne appli
Application très utile pour progresser en calcul mental sans (trop) se fatiguer la tête.
Simple et excellent
Superbe appli pour comprendre et progresser.
Calcul mental calcul royal
Top application pour jouer à calculer de tête Une petite revanche sur les calculettes ou comment savoir que si 48 x 12 = 96 c est qu il doit y avoir eu une faute de frappe :)
Probably nice ...
Unfortunately the download is in Korean (?). Cant see how to switch it to another language. That way the app is useless for the majority of users.
