    I'll explain this very slowly.

    You should (hopefully) know how to count.

    If you are at 1 on a number line. (1 2 3 4 5 6...)

    ↑ you are here

    And you need to add 1 more. You would move one space on the number line to the positive end.

    (1 2 3 4 5 6...)

    »»» positive numbers get larger when you move more to the right.

    And if you move 1 space from the 1 you would land on 2.

    (1 2 3 4 5 6...)

    *»˝

    Starting on the 1 and moving 1 space forward on the number line leaves you on 2. Hence 1+1=2

    1 + 1 = 2.

  • 2

    and by the way @ Wile you didn't prove anything since you got 2=1 that proves that a doesn't equal b and therefore it is an invalid problem stop trying to be a smart butt and confuse little children into thinking that they are smart/can prove adults wrong

    1 + 1 = 3

    Proof:

    Given: a = b

    a² = ab.........................(Multiply both sides by a)

    a² - b² = ab - b...............(Subtract b² from both sides)

    (a + b)(a - b) = b(a - b)....(Factor both sides)

    a + b = b.......................(Divide both sides by a - b)

    b + b = b.......................(Sub b for a since it is given that a = b)

    2b = b...........................(Combine like terms)

    2 = 1.............................(Divide both sides by b)

    Since 2 = 1, they are interchangeable, so

    1 + 1 = 2 + 1 = 3

    QED
