The Soviet two-man set an example in a minute, see if you can master it

No matter how confident adults are, simple examples It is not always easy for them. But don't be ashamed of it! Time passes and even basic school knowledge is forgotten. This is normal, because most of them we simply do not use.



Let's make a deal. Today, you're gonna try to rein in a couple of high school examples with a snag. If you don’t solve all of them correctly, you won’t get upset. Let it be a little shake-up for the mind. Try to distract yourself from worries and household affairs. It's especially valuable now!

So the first mathematical example is right in front of you. Study it carefully and do not rush to draw conclusions. Remember the sequence of actions in such examples. Let’s assume it was a small tip from our editorial board.



For a better effect, you can see how long it will take you to solve this simple example. Second graders, for example, decide in a couple of seconds. All right, all right, it could take two guys about a minute. And you?



Now let's get this straight. In such examples, it is very important to remember the order of performing arithmetic actions. First we look at whether there is multiplication or division in the example. As you can see, there are such actions. It turns out that 1 × 0 = 0. And 2 ÷ 2 = 1.

Return to the main part of the example and perform the actions in turn. So first we subtract zero from six, and then we add one to the resulting six: 6 - 0 + 1 = 7. That's all the wisdom!



By the way, if there were brackets in this example, we would first decide what is inside them. But they did not exist, so we moved on to the calculations of the second stage, that is, division and multiplication. As you can see, there is really nothing complicated about this example. Now you can easily solve any problem of the same complexity. Yay!

Selection of examples with a clog

1. In this example, you may be confused by the fractional number 0.5. And it is not surprising that the hand immediately wants to reach for the calculator. How to divide it into such a natural fraction? I believe you can do this. If you don’t, go down there and find the answer.
   
   
   
   
2. It's simple. Think about what we discussed at the beginning of this article. The order of performing arithmetic actions will help you understand everything. Go ahead!
   
   
   
   
3. In this example, you need to divide the number by fraction. I wonder, do you remember how to do that?
   
   
   
   

Answers.

1. Anyone who has experienced mathematics in life knows that dividing by 0.5 is like multiplying by 2. Therefore, we get a very simple and understandable example that will not be difficult to solve.
   Namely: 30 × 2 - 1 = 60 - 1 = 59.
2. We deal with brackets, and then take turns to solve each action. The result is: 24 ÷ 6 (4 – 3 + 2 – 1) = 24 ÷ 6 × 2 = 4 × 2 = 8.
3. To solve this example, you need to recall another simple feature from the school curriculum in mathematics. Dividing a number by a fraction is the same as multiplying it by the same fraction, having previously changed the numerator and denominator places. Then our example gets a slightly different, but more understandable look: 9 - 3 * 3 + 1 = 9 - 9 + 1 = 1.

The examples are over for today! I hope you managed to dilute the atmosphere of routine everyday life and remember school days. How many examples did you manage to solve correctly? I'll see you in the comments!
