    Bronze:
    Add two even numbers together will always make an even number?
    True because 2+2=4 18+18=36 4+4=8 8+8=169+9=18. And there all even numbers.

    Plantium:
    2+3+4=9
    3+4+5=12
    4+5+6=15
    5+6+7=18.

  2. Hadiya M.

    Bronze:
    Yes it is true because when whee add two even numbers together it will always make an even number.
    For example
    8+6=14
    10+4=14

    Silver:
    10+26=36
    9+27=36
    8+28=36
    7+29=36
    6+30=36
    5+31=36
    20+16=36

    Gold:
    10p+10p+5p=25p
    10p+5p+5p+2p+2p+1p=25p
    10p+10p+1p+1p+1p+1p+1p=25p
    5p+5p+5p+5p+2p+2p+1p

    Platinum:
    2+3+4=9
    3+4+5=12
    4+5+6=15
    5+6+7=18
    6+7+8=21
    I noticed that it has a patern and the answer is a 3 timetable.

    1-true for example 64+32=96
    2-
    34+2=36
    35+1=36
    18+18=36
    30+6=36
    20+16=36
    33+3=36
    26+10=36
    3-
    20p+5p=25p
    10p+10p+5p
    10p+5p+5p+1p+1p+1p+1p+1p=25p
    50p-25p=25p
    20p+2p+2p+1p=25p
    10p+5p+5p+5p=25p

    4+5+6=15 this pattern is of odd numbers.

    1. Awais J.

      Platinum=This pattern is adding 3 each time

    True ,4+6=10
    Silver
    2+34=36
    3+33=36

    2+2+2+2+2+2+2+2+2+2+2+2+1=25
    Platinum
    4+5+6=15,So 9,12,15 then 18,21,24,27 that means counting in 3 .

    Correct because in the two times tables it gains up to an even number. So the result can always be divided by two.
    4+6 = 10 (even), 10/2 = 5
    6+8= 14 (even), 14/2 = 7
    8+4 = 12 (even), 12/2 = 6

    3+33=36 13+23=36 23+13 = 36
    4+32=36 14+22=36 24+12 = 36

    7+29=36 17+19=36 27+9 = 36
    8+28=36 18+18=36 28+8 = 36
    9+27=36 19+17=36 29+7 = 36
    10+26=36 20+16=36 30+6 = 36

    31+5 = 36
    32+4 = 36
    33+3 = 36
    34+2 = 36
    35+1 = 36

    5p+5p+5p+5p+5p =25p
    10x2p + 5x1p=25p
    15x1p+ 5x2p = 25p
    50p – 10p – 10p – 5p = 25p
    10p + 10p + 10p – 5p = 25p

    Platinum
    4+5+6 =15, then 18 and then 21 because the pattern is counting in 3rs
    9,12,15, 18, 21, 24, 27, 30, 33, 36, ….

    20p + 5p = 25p
    10p + 10p + 5p = 25p
    5p + 5p + 5p + 5p + 5p = 25p
    20p + 2p + 2p + 1p = 25p
    10p + 10p + 2p + 2p + 1p = 25p
    ( I helped Faris with this as he really struggled with all the challenges)

    I notice the number sentences start with the middle number then the next number after that and if you look at all the numbers together you can see a pattern in the columns.
    All the number sentences end in the 3 times table. I used my Time table
    card.
    1 x 3 = 3
    2 x 3 = 6
    3 x 3 = 9
    4 x 3 = 12
    5 x 3 = 15
    6 x 3 = 18
    7 x 3 = 21
    8 x 3 = 24
    9 x 3 = 27
    10 x 3 = 30
    11 x 3 = 33
    12 x 3 = 36

    The next number number in the sequence would be 15.
    The pattern I noticed was the answers going up in 3s.

    Bronze – yes it’s fact because even numbers can always be split into 2 equal numbers.
    E.g
    10+10=20, if you split 20 you have two 10’s. 2 +2 = 4

    Any even number can plus any other even number will always equal an even number.

  19. Aiza B.

    Bronze: yes if we add two even numbers together the answer will be always even,so this statement is true e.g.
    4+2=6 so 4 is a even no and 2 is a even no too so answer is even aswel which is 6.
    Silver:
    We can make 36 number by adding up different numbers,
    1+35=36
    2 +34=36
    3+33=36

    It shows we r adding 3 up in every answer so it is a 3 times table.

  20. Havin A.

    Bronze.
    The answer is true because even is 2,4,6,8,10,12,14,16,18,20,22,24.

    I’ve noticed there is a pattern and the pattern is (2,3,4,5) (3,4,5,6) (4,5,6,7)

  21. Eesaa A.

    Bronze:
    It is true because:
    2 + 2 = 4 and 12 + 12 = 24. So, if we add any even numbers together it will always equal an even number.

    Silver:
    Some ways to make 36 are:
    36 + 0
    35 + 1
    34 + 2
    33 + 3
    32 + 4
    31 + 5
    30 + 6
    29 + 7
    28 + 8
    27 + 9
    26 + 10

    Gold:
    Some ways to make 25p are:
    10p + 10p + 5p
    50p – 10p – 10p – 10p + 5p
    5p + 5p + 5p + 5p + 5p
    10p + 10p + 1p + 1p + 1p+ 1p + 1p
    10p + 10p + 2p + 2p + 1p

    Platinum:
    2 + 3 + 4 = 9
    3 + 4 + 5 = 12
    4 + 5 + 6 = 15
    5 + 6 + 7 = 18
    6 + 7 + 8 = 21
    I notice that it is going in number order like 1 2 3. I also notice adding on 3 every next sum.

  22. Sumayyah A.

    Bronze – It is true because even numbers can always be split into 2 equal numbers.
    example – 10+10=20, if you split 20 you have two 10’s.

    Silver
    31+5=36
    17+19=36
    21+15=36
    33+3=36
    10+26=36

    10p+10p+5p

    10+5+2p+2p+2p+1p+1p+1p+1p
    5p+5p+10p+1p+1p+1p+1p+1p

    Platinum
    2+3+4=9
    3+4+5=12
    4+5+6=15
    5+6+7=18

    The difference between all the answer is 3.

  23. Jebrin Y.

    Bronze:
    1- It is true. This is because 2+2 equals 4 and 10+10 equals 20.

    Silver:
    1- 26+10
    31+5
    21+14
    34+2
    35+1
    33+3
    24+12

    Gold:
    10p+10p+5p
    5p+5p+5p+10p
    50p-10p-10p-5p

    Platinum:
    1- 4+5+6 equals 15.
    The pattern is that the last two numbers get moved on and added with the next biggest number.
    The next sequence would be 5+6+7.
