2 I disagree with that you can put all of the counters in the 💯s coulum

7+5=12

8+4=12

9 +3=12

6+6=12

2+10=12

11+1=12

589-70 is not equal to 582

He is wrong because you can have more then 10 counters.

1) sometimes

2) 3 + 9

4 + 8

5 + 7

6 + 6

7 + 5

8 + 4

3) I don’t agree because you can still add the extra ones from the tens and ones colum to the hundreds coloum.

4) 459

Balraj is incorrect because 589- 70 is 582 no that would be 589 – 7 = 582.

It is wrong because you took away seven ones then Seven tens.The real answer is 519.Here is the question it is 589-70=519.

Captain Conjecture is not right.

Largest 3 digit number that we can make by changing tens is 891 and not 811.

Possible numbers in increasing order are..

NO because he took away 7 ones from 589.But the answer is…..2.

589-70=519

1. They did not takeaway 70 they said 582 but that was wrong the real answer it is 512

259

452

Always because 9+3,8+4 and 6+6 makes 12.

Wrong

589-70=519 is the real one.

No you can make 1000 using ten counters.

2 5 9 4

You can make

249 259 294 295

459 429 492 495

594 592 529 549

945 954 924 925 942 952

1.Because 5+7=12 where 2 is in the ones column. Another example to prove it 15+17=32.

2. 589-70=519 because 0 takeaway 9 is 9 and 7 takeaway 8 is 1 and there is nothing to takeaway from 5.

3.No, because 999 is the largest 3-digit number.

589-70=582 is not correct the real answer is 519.

I do agree because they used most dots in the 100s column

Balraj is incorrect because 589- 70 is 582 no that would be 589 – 7 = 582. So that’s basically never. He’s incorrect because the largest number that you could make is 1,000 instead of 800. So that’s sometimes.

003,009,028,050,305 and 450

10 more than 2 is 12, 10 less than 2 is -2. 10 more than 5 is 15 10 less is -5. 10 more than 9 is 19 10 less is -9. 10 more than 4 is 14 10 less is -4. That’s basically sometimes
