  1. bronze 53 is the odd one out because it is a 2 digit number and the other ones are 3 digit and the 3 digit numbers are even and 53 is odd.
    SILVER
    50+63= 113
    153+48 = 201
    98+276=374
    Gold
    i think it is 24
    platinum

    i predict it is true.

  2. Gold: 2×20=40 So the answer is 40.

    Platinum: 1. True, because in the 2 x table you skip the odd numbers. If I count from 2 to 10 the number I will have are 2, 4, 6, 8, 10 which are even numbers.

    2. False, because when I counted backwards starting from 93 the nearest numbers were 41 and 45 but 43 wasn’t there.

  3. Bronze:
    53 is the odd one out because it is made of two digits.
    Silver:
    113=100+13 201=130+71 374=150+224
    Gold:
    I think the number you were thinking was 24 because 40-2+10\2=24.

  4. bronze:the odd number is 53 because 53 doesnt have 3 numbers

    silver
    100+13=113
    200+1=201
    300+74=374

    gold
    i prediuct that the number is going to be 40

    platinum
    1.true beacause 2 and 10 are even numbers.counting 2s in steps of 10 will be even numbers only

  5. bronze
    1]53 is the odd one out because the other ones are even

  7. Bronze
    53 124 230
    53 because it is a 2-digit number and it`s an odd number
    Silver
    113 201 374
    112+1 197+4 161+213
    Gold
    24 because:
    2×20=40
    40-2=38
    38+10=48
    half of 48=24
    Platinum
    True because 2 and 10 are eaven numbers.If you add eaven add eaven you will always get an answer that is eaven.

    False because if you count backwards in 4s you will only say the numbers 49,45 and 41 and miss out 43.

  8. silver
    50+63=113
    153+48=201
    98+276=374
    gold
    2*20=40
    40+2=42
    42-10=32
    32*2=64
    nr is 64
    platinum
    2-12-22-32-42-52-62-73
    37-41-45-49-53-57-61-65-69-73-77-81-85-89-93
    nr 43 dose not come

  9. Gold:
    My answer is 2 x 20 = 40
    Going backwards
    I add 2. Opposite of add is subtract
    40 – 2 = 38
    I subtract 10. Opposite of add is subtract
    38 + 10 = 48
    I double it. Opposite of double is half
    Half of 48 is 24
    The number your thinking of is 24

  10. Bronze:
    124 and 230 are from the 2 times table, whereas 53 is not and the odd one out is 53.
    124 and 230 are even numbers.
    53 is a odd number.

    Silver:

    (113)➡️ 50 +63 = 113

    (201)➡️ 153 + 48 = 201

    (374)➡️ 98 + 276 = 374

    Gold:
    2 x 20 = 40
    40 + 2 = 42
    42 – 10 = 32
    32 x 2 = 64

    64 is the number your thinking about.

    Platinum:

    2 ➡️ 12 ➡️ 22 ➡️ 32 ➡️ 42 ➡️ 52 ➡️ 62 ➡️ 72
    It is true it goes up in even numbers.

    37 ➡️ 41 ➡️ 45 ➡️ 49 ➡️ 53 ➡️ 57 ➡️ 61 ➡️ 65 ➡️ 69 ➡️ 73 ➡️ 77 ➡️ 81 ➡️ 85 ➡️ 89 ➡️ 93

    43 does not come in the numbers if your counting four backwards from 93

  11. BRONZE
    53 is the odd one out because you can’t share it.
    GOLD
    HE IS THINKING OF THE number 42.
    PLATINUM
    the first one is true because you count in the 2 times table.
    the second one is false because you have to count in 2s a few more times.

  12. Bronze
    The odd one is 53.
    Silver
    65+48= 113,100+101=201,209+165=374.
    Gold
    The answer is 40.
    Platium
    True because 2 time table are even.
    False because it will be 99.

  13. BRONZE CHALLENGE:1.53 is a odd number beacuse it ends in a three.

    SILVER CHALLENGE:1.113
    100+10+3=113
    2.201
    200+1=201
    3.374
    300+700+4=374

  14. bronze
    the number that is the odd one out is 53 because the other two have hundreds and 53 hasn’t got a hundred.

    gold
    the answer he was thinking of was 40.

  15. Bronze:
    1.the odd number out is 53 because you can’t share it and it’s not in the 2 times table.
    Silver:
    1.113,201,374
    Gold:the numer the whale is thinking is 40

  16. Bronze
    I think it is 53 the odd one out because 124 and 230 is in the 6x table.

    Silver
    93
    34+59=93
    72
    36+36=72
    96
    43+43=96

    Gold
    It is 32 because double 20 is 40 then it says subtract 10 then that is 30 after that it says add 2 then 30+2=32

    Platinum
    True because 2x table are all even numbers.
    False because when I counted backwards from 93 and it didn’t say 43.

  17. BRONZE
    The odd number is 53 because you can’t share the number
    SILVER
    1.113,114,115
    2.201,202,203
    3.374,375,376
    GOLD
    The number the wale is thinking of is 40
    PLATINUM
    1.The answer is true because the 2 times table has all the even numbers
    2.The answer is false because you have to count more backworts

  18. bronze challenge:
    1.53 is an odd number because it end’s with a three and you can’t share it so it mean’s it is odd.

    124 is not an odd number because it end’s with a 4 so it mean’s you can share it so it means it is even not odd.

    3.230 is not an odd number it is an even number because if some one has a party and there were 0 sweets it would be fair because no one gets one.

    silver challenge:

    1.113 100+13=113

    2.201 100+101=201

    3.374 261+113=374

    gold challenge:

    1.the number was ten because 10-10=0+2=2

    platinum:

    1.yes it is true because they all end with the number 2 and 2 is an even number.
    2.it is false because you will only be able to get the number 45 and the number 49 and 41.
