BRONZE:
Alex runs 800 meters
Whitney runs 10X further
800X10=8000
10X times further so you take away 800 so the final answer is:
7200
SILVER:
the prime numbers are
2,3,5,7,11,13,17,19,23,29
so the two missing numbers are 17 and 29
GOLD:
factors of 12
1 x 12 = 12.
2 x 6 = 12.
3 x 4 = 12.
4 x 3 = 12.
PLATINUM:
11-7=4

If Alex ran 800 meters and Whitney runs 10 times more than Alex she has ran 8000 ,I know this by 800 × 10 which equals 8000 ,whenever you times you will always move the digits one place to the left.This means that Whitney has ran 7200 meters more than Alex and I know this by adding 800 and 7200 together which will equal 8000.
Silver:
The missing prime numbers Max missed are,17 and 29
Gold:
This is another way to make arrays for 12 — — — — This example shows 4 × 3 or 3 × 4 – 12
Factors of 12 are:
1,12,2,6,3,4 – 1 × 12 , 2 × 6 , 3 × 4
Factors of 24 are:
1,24,2,12,3,8,4,6 – 1 × 24 , 2 × 12 , 3 × 8 , 4 × 6
Factors of 36 are:
1,36,2,18,3,12,4,9,6,
Platinum:
11 – 7 = 4 which is a squared number .
Squared up to 100 are:
1
4
9

BRONZE
8000
because I know that 800×10=8000.
———————————————————-
SILVER
The numbers that Max are missing are 17&27. I know this because they are a prime number
———————————————————-
GOLD
Factors of 12:
1,2,3,4,6&36 because you can divide any of those numbers.
———————————————————-
Factors of 24:
1,2,3,4,6,8&12
EXAMPLE:
24 divide by 2=12
———————————————————-
FACTORS of 36:
1,2,3,4,6,6,12,18& 36

Whitney ran 8000 meters however Whitney also ran 7200 more then Alex I can prove this by using my time table knowledge and 800 x 10=8000 I know this because you just have to move the digits 1 forward if we were dividing out answer would of been 800.
Silver
A prime number is a number that the only factors are 1 and itself an example is 7. 7’s factors are 1 and 7 which makes it a prime number and 18 is not a prime number which we call a Non-prime number you can do 2 x 9 which equals 18. But the answer for this is 17 and 29 it can’t be 28 because 13 x 2=28 and it can’t be 16 because 4 x 4=16 it can’t be 30 because 10 x 3=30 and it can’t be 18 because like I showed 2 x9=18
Gold
Here is another example of an array which shows 12(4 lots of 3 also known as 4 x 3=12)
. . . .
. . . .
. . . .

Above shows 4 x 3 or you can say 3 x 4 which they both equal 12
Factors of 12 are: 1,12,2,3,4 and 6
1 x12=12
2×6=12
3×4=12
Factors of 24 are: 1,24,2,3,4,6,8 and 12!
1 x24=24
2 x12=24
3 x 8=24
4 x 6=24
Factors of 36 are: 1,36,2,3,4,6,9 12 and 18!
1 x36=36
2×18=36
3×12=36
4 x 9=36
6 x 6=36
There is no 5’s in this because all of the numbers in the 5 times table either end in a 5 or a 0 for example 5 x 10=50 or even 5 x 5=25
Platinum
This can either be 11 – 7=4 or it can be 13 – 4 =9(11 and 13 are prime number and 4 and 9 is a square number)
Sorry that this came in late!

The question is eleven – seven= four
I found out that ten – one -hundred then subtracting seven from a prime number to make a one – digit number then I crossed off all of the answers with two -digit numbers the only prime numbers left were thirteen and eleven. I then did thirteen– seven= six, but six wasn’t a square number. Then, I did eleven – seven= four then I got my answer
the square numbers from one – One-hundred are
One
Four
Nine
Sixteen
Twenty-five
Thirty-six
Fourty-nine
Sixty-four
Eighth-one
One-hundred

11 – 7 = 4. 11 is a prime number and when you take 7 away from it, it equals 4 which is a square number.

Whitney runs 7200 meters further than Alex. I know this because 800X10=8000 and 8000-800=7200
Silver
3,5,7,11,13,17,19,23,29and31 are all prime numbers
So max missed 17 and 29

Platinum :
1) The question is 11 – 7 = 4.
2) I found this out by writing the prime numbers from 10 – 100 and then subtracting 7 from the prime numbers to make a 1 – digit number. Then I crossed of all

Bronze:
It could be 900 because if 100 + 800 = 900
Then the answer is 900.
Silver:
17 and 29 because you can’t have any factors to times by to get that number (what I’m saying is ,the only factors are 1 and itself).
Gold:
The factors of 12 are :
1,12,2,3,4 and 6.
The factors of 24 are:
1,24,12,2,3,4,6 and 8.

Silver
27 and 17
Gold
factors of 12
1,2,3,4,36 and 6 because you can divide twelve by any of those numbers.
factors of 24
1,2,3,4,6,8, and 12 because you can divide these numbers by 24 like 2 divided by 12 = 24.
factors of 36
1, 2, 3, 4, 6, 9, 12, 18, and 36!!
Example:
12 divided by 3 = 36
Platinum
13-7=6
11-7=4
This is all I could do because if you use a prime number and minus it by seven and it becomes something for example 13-7=6 there is entirely no way of how to put a prime number then minus it into a squared number.
