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.

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.

9+3=12 1.
7+5=12
8+4=12
6+6=12
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

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

22. Aleena M.

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
