    The correct answer would be 10 right?

    40 × 0.25 = 10

    There is no plus in there and empty space turns into a multiplication by default.

      No, that’s a way to represent a fraction’s integer part.

        Depends on culture and level of education. For someone who comes from a culture where we use decimals, I’d interpret this in the math/physics class way, i.e. 10.

          Yes, with no previous context or warning I would assume the same, but regardless, the notation exists.

          Might be. I’ve never seen it used that way, though, I know that some people prefer parentheses around the fraction to the right of integers.

          I learned at grade/primary school, it’s useful as a teaching tool for fractions. Although, I do recall using something similar for partial fractions in college.

          That said, even Wolframalpha appears to disagree, which I find mildly funny if what you say is true.

          In wolfram alpha they call it mixed fraction or number.

      Yes, but no. That notation is the dumbest one ever. Everywhere else a juxtaposition implies multiplication, except for fractions with integers to the left.
