10 Year olds maths homework - Can anyone on here do it?
Here you go!
Using the digits 0 to 9, once each only, make five different numbers that:
Assignment 1) divide by 7
Assignment 2) are prime
Good Luck!

There's no 6 in your first set of answers, plus I think you need to use the zero too.

nah just trial and error guessed the first few then figured one of the numbers must be a 3 digit and a Maths degree helps!
Ill leave the prime numbers to you guys!

The question cannot use all the numbers to answer both assignments - it aint possible, as you will need more numbers than provided to do both assignments as such it is surely just...
Prime numbers - 1, 2, 3, 5, 7
Divisible by 7 - 0, 7, 14 , 28, 63
My best guess, based on the sketchy wording of the question

I think you're supposed to use all the numbers 0-9 for assignment one and then again all the numbers from 0-9 for assignment two.

Wow - that is a tough question for a 10 year old then!
Bugger that. I think I will stick with the far easier Quantum Physics! I have just worked out what Quarks are!!!
