Explications étape par étape :
1)
Think of a number. 4 12 x
Multiply it by 0,25. 4X0,25=1 12 X 0,25= 3 x / 4
Add 5. 1 + 5 = 6 3 + 5 = 8 x/4 + 5
Multiply by 4. 6 X 4 = 24 8 X 4 = 32 x + 20
Substract 10. 24 -10 = 14 32 - 10 = 22 x+20-10=x+10
Substract the initial number. 14 - 4 = 10 22 - 12 = 10 x+10-x= x
2)
Le résultat final est toujours égal à 10
