Je suis en train de lui demander de démontrer des théorèmes (forcément c'est simple pour lui) et aussi de savoir comment il expliquerait à un enfant certains concepts comme les nombres premiers :
A prime number is a whole number (a number without any fractional or decimal part) that is greater than 1 and has only two factors: 1 and itself. For example, the first few prime numbers are 2, 3, 5, 7, 11, and 13.
One way to explain this to a 10 year old is to use examples. For instance, you could say that the number 2 is a prime number because it is only divisible by 1 and itself. You could also say that the number 4 is not a prime number because it is divisible by 1, 2, and 4.
Another way to explain it is to use a visual aid, such as a number line or a list of numbers. You could point out the prime numbers on the number line or in the list, and explain that these are the numbers that cannot be divided evenly by any number other than 1 and themselves.
You could also encourage the child to try to find prime numbers on their own, using the rule that a number is prime if it is only divisible by 1 and itself. This can be a fun way to reinforce the concept and help the child develop their math skills.
