  1. I chose 8 and 9
    8×8 = 64
    9×9 = 81

    81-64 = 17

    I chose 5 and 6
    5×5=25
    6×6=36

    36-25=11

    I chose 7 and 5
    7×7=49
    5×5=25

    49-25=25

  2. so its crazy but say i have 2,3
    2 squared is 4 and 3 squared is 9
    9-4=5 and the wierd part
    2+3=5 and so that is how you can add squares and find them
    also if you dont know sq

  3. so its crazy but say i have 2,3
    2 squared is 4 and 3 squared is 9
    9-4=5 and the wierd part
    2+3=5 and so that is how you can add squares and find them
    also if you dont know your second squared number try this
    4+2+3=9 also helpful.

  4. on the school board we found an easier way to find square numbers this is how you do it:

    for example if you want to find the square number of 8 find out what the number before your number in this case its 7 and it equals 49 then you do 49+7+8=64 and 64 is the squared number of 8.

  5. on the board at school we worked out an easier way to find square numbers e.g. 12×12 for example if you times a number by itself you can find the difference between the squared number and the number that you get by timsing it by itself.

  6. 6,7

    6 x 6=36

    7 x 7=49

    49-36=13

    6 + 7=13

  7. i have notice that the difference between the numbers for eg 64 81 what ever the anwser = the difference between them

  8. its hard and many people don’t know what this type of maths is but for instance.
    6,7 6×6=36 36+6+7=49

    7×7=49 49-36=13
