How well did you learn the school curriculum? In this case, we are talking about the basics of arithmetic. Do you want to test your knowledge? We bring to your attention a problem from the textbook for the second grade.
So, before your eyes you have this example:
Were you able to solve it? Let’s check the answers.
At school, we were taught that those actions that are in brackets will be performed first.
17-5=12 and 9-6=3;
So far everything is clear, right? Recall that if there is no sign between the number and the bracket, then you need to multiply.
And since division and multiplication are considered equivalent actions, therefore they are performed in order.
12:2×3=6×3=18.
