Users write Now: BluCari • 10 months ago • edited I understood why the calculator gives 2 + 2x2 8 in the example because it counts 2 + 2 first and then only 4x2, as it were, the first 2 + 2 example solves first and then the other does the answer and it turns out 8 I know it's obvious, but some don't.
