    There’s just 5 lots of 2. If it’s hard then think of x being just a bunch of + smooshed together. So

    2 + 2 x 4

    expands to

    2 + 2 + 2 + 2 + 2

    or contracts to

    5 x 2

      You’ve completely not understood that order of operations is an arbitrary convention. How did you decide to expand the definition of multiplication before evaluating the addition? Convention.

      You can’t write 2 + 2 ÷ 2 like this, so how are you gonna decide whether to decide to divide or add first?
