The calculation is incorrect because instead of taking away you adding so the answer will be 21. The reason why I think 21 is because 4-3=1, 4-2=2 and 1-0=0 so the answer is 21.

The answer is incorrect because you can’t do 144-123 the answer is not 267.If you calculate it properly and check again .then you notice were your mistake is. 144-123 the answer is 21.

bronze challenge
The answer is incorrect because the person who did this question the person was supposed to subtract but he didn’t look that he was subtracting 144 -123 which is 21.

Firstly for this question you need to add £25.00 and £10.00 which is 20 plus 10 which is 30 and add the 5 which is 35.Next £1 =1.26 euros so you have to times it by how much money you got in pounds which is £35 x 1.26=44.1

The answer is incorrect because you are adding instead of subtracting. The real answer is 21 because 4-3=1 and 4-2=2 and 1-1=0 so the answer is 21.

The answer is incorrect because real answer can’t be higher
than the numbers you subtract by. 144

1.£25 + £10 = £35
2.£35 x 1.26 = 44.1

I think the answer is two.

I think it is incorrect because four – three
is one and fourty – twenty is twenty so twenty
+ one is twenty one.

I think the answer is incorrect because in the sum it tells me to subtract not to add.The answer is 21.144 – 123 = 21.Also to correct the calculation people need to use correct symbols.so the
sum should be 144 + 123 = 267.

gold challenge
i think 2

it is incorrect because when you look at the number at the begining it has a 1 and the answer has a 2 at the start and it is ment to be lower not higher the real answer is 21

Actually there are 6 patterns.

Key

1=colour 1 11222211,22111122,12211221,21122112,21211212,12122121.

2=colour 2

Bronze challenge

The answer is not 267 because 4-3=1 4-2=2 and 1-1=0 so the answer is 21.Here is an example of 144-123

144 4-3=1

-123 4-2=2

021 1-1=0 Therefore the answer is 21

Silver challenge

£1=1 euros

1.26×35=44.1

There are six different ways.

key

1 = colour 1

2 = colour 2

Different ways:

12122121,21122112,11222211,22111122,21211212,12211221
