The calculator system is finished from the back to the front. And the mobile is over from the front to the back. Such as: Calculator 6 ÷ 2 (2 + 1) 6 ÷ 2 × 3 (I added one to two, three and multiplied by the back of the back) 6 ÷ 6 (two times three) 1 (divided by six by six) Mobile 6 ÷ 2 (2 + 1) 3 × 3 (I divided by six and divided the two inside the bucket into three) When you lift the bucket, it will multiply 9 Note: calculatot answer will be correct and mobile will be wrong)
Why you calculated by back to back? It's should count from left to right. Q: 6÷2(2+1) =? A: 6÷2(3)...Here () = ×. So, it will become 6÷2×3= then calculated it from left to right.. (6÷2)×3 = ? 3×3=9. So the answer is 9. Why you should to calculated near the equivalent first. It's wrong already. My calculator also answer is 9.
