  1. 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
    395
    383
    328
    250
    209

  2. 3+9=12
    4+8=12
    5+7=12
    6+6=12

    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..
    109
    152
    228
    233
    315
    454

    259,295,249,245,294,254
    594,542,529,549,524,592
    924,954,925,952,945,942
    429,425,459,452,492,495

  3. 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

  4. 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.

    5. 249

    452
    442

  5. 7+5=12
    9+3=12
    8+4=12
    6+6=12
    5+7=12
    3+9=12
    4+8=12
    589-70=582 is not correct the real answer is 519.
    I do agree because they used most dots in the 100s column

  6. 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
