3,6,9,12,15,18,21,24,27,30,33,36.
Instead of 12 he took 13 and he added 3 which equals 16 he added 3 which equals 19.
Silver
48 because 8×6=48.
She would get 28 because 4×7=28.
63 because 7×9=63.
6 because 54/9=6.
30 because 5×6=30.
£3 because £21/£7=£3.

The mistake that Tiny made is that he is keep on adding one more to the 3 times table.

1) he has 48 chocolates altogether
6×8 = 48
2)In 1 week she will get 28$
4×7=28$
3)The farmer planted 63🥕
7×9=63
4)Mary downloaded 6 apps in 1 week
54•9=6
5)There are 30 blossoms in total
6×5=30
6)You will save 3$ in one day
21•7=3 -
1 so if josehf has 8 bags and 6 chocolate bars in each bag then it would be 8X6=48.
2 7X4=28
3 9X7=63
4 54/9=6
5 5X6=30
6 21/7=3

Tiny is incorrect because he added a 4 instead of a 3 so 19+3=22 but tiny did 19+4=23 so I disagreeSliver
There are 48 chocolates because 6×8=48 so There are 48 chocolates
2. Sarah gets £28 a week because if there are 7 days in a week so 4×7=28
3. There are 63 carrots because if there are 9 carrots in each row then 7 rows then that’s 7×9 =63 so 73 carrots.
4. Mary downloads 6 apps every week because 54 inverse is 6×9=54 so in 9 weeks there are 6 apps each week
5. Joe plants 30 flowers because if there are 5 bunches of 6 that is 5×6=30 so jor plants 30 flowers
6. You would get £3 in one day because there are 7 days in a week that means that 21÷7=3 so £3Gold
Always because 9=9 1+8=9 2+7=9 3+6=9 4+5=9 5+4=9 6+3=9 7+2=9 8+1=9 9+0=9 and 1+0+8=9.
Platinum
You can do 9×8=72 because 8 and 9 is less than 17 and 9+8=17 so that is the correct answer.

BRONZE
Tiny’s mistake is that he did 3,6,9 which is correct but 13,16,19 is incorrect because in times tables you have to add the number but 9 add 3=12 so he is incorrect .
SILVER1. The answer is 48 . I know this because there are 8 chocolates and 6 bags and in order to find the answer we need to do 8×6 because there are 6 groups of 8 so 8×6=48.
2. She will have £28. This is because she gets £4 each day and there are 7 days in a week so we need to do 4×7 because there are 7 groups of 4 so we have to do 4×7 and it =28.
3. There will be 63 . It is my answer because the farmer plants 7 plants and there are 9 rows so we have to do 7×9 because there are 9 rows of 7 so we have to do 7×9 and it =63.
4. Mary downloaded 6 apps . This is are answer because she downloads 54 apps and she did that for 9 weeks so we need to do 54 ÷9 because there are 9 groups of 54 so 54÷9=6.
5.There will be 30 flowers. This is because there 6 flowers in each bush and there are 5 bushes so we have to do 6×5 because there are 5 groups of 6 so 6×5=30.
6.£3. This is because 21 ÷ 7 =3
GOLD
Sometimes because in 99 you do 9±9 it equals 18.

Sometimes because 9+9 is not 18.-
Good effort, Zenat.
Try the pattern with all of the multiples of 9…
9 (9+0=)
18 (1+8=9)
27 (2+7=9)
36 (3+6=9)
45 (4+5=9)
54 (5+4=9)…

1) Tiny’s mistakes are he counted wrongly like 13,16,19 and 23. He supposed to count 3,6,9,12,15,18,21,24,27,30,33 and 36.

1) 8×6=48
4×7=28
9×7=63

21÷7=3

1) Sometimes true because. Example 99 is a multiple of 9 but not a sum of 9 because 9+9=18.

1) 9 and 8 is his number. I worked this out because 8+9=17 and 9×8=72. -

Always because if you write 47➗7=7 and you wanted it to be in the nine time table you will think it’s in the 7 time table

1. 8 x 6 = 48 there are 48 chocolate.
2. 4 x 7 = 28 so she has £28 if she does all her chores.
3. 9 x 7 = 63 so the Farmer will have 63 carrots.
4. 54 divided by 9 = 6
5. 6 x 5 = 30 so he has 30 flowers.
6. 21 divided by 7 = 3 so you have £3 each dayGOLD
sometimes because 9 + 9 is 18 not 9 and 99 is 9 + 9

1 )48 because 8 ✖️ 6=48
2)28 because 4 ✖️ 7=28
3) 63 because 9 ✖️ 7=63
4) 6 because 54 ➗ 9=6
5)30 because 5 ✖️ 6=30
6)3 because 21 ➗ 7=3
Gold
Sometimes because 27 is not a digits of 9 but 45 and 81 is
Mo number are 9 and 8 you just have to change the symbol to + and ✖️-
Can you explain the mistake that Tiny made in Bronze, Waniya?

The mistake is 13,16,and 23
It should be 12,15,27 and 30 -
Bronze:
The mistake is that 13,16,19 and 23 are not made of 3s.
Silver:
1. 48 because 8 x 6 = 48
2. 28 because 4 x 7 = 28
3. 63 because 9 x 7 = 63
4. 6 because 54 ➗ 9 = 6
5. 30 because 5 x 6 = 30
6. 3 because 21 ➗ by 7 = 3
Gold:
Sometimes because 27 does not have a digit of 9 but 99 does.
Platinum:
Mo’s numbers are 9 and 8 because you just have to change the symbol with ➕ and ✖️.
9+8 = 17
9 x8 = 72-
Bronze
Tiny mistake was he add one more to each number so instead of 13 its 12 and instead of 16 and 19 its one number less but 23 is to more than 21 which is the actual number
Silver
1.8×6=48 Gold
2.4×7=28 sometimes because for 45 divide
3.9×7=63 by 9 is equal to 5l
4.54÷9=6
5.6×5=30
6.21÷7=3 -

9×8: this is because 9+8=17 which is mo’s sum and 9×8=72 which is mo’s product.

Sometimes you see if you times 9 2 times you would have 18 which has a 10 and 8 but there is no trace of the number 9 so sometimes
