There are many people who wonder about this example because it seems so confusing. But in fact it can be solved by anyone who hasn’t skipped math at school. Even if you didn’t like it much, they still made you learn the basic rules.
One has only to figure them out – and problems are solved with great pleasure.
The elementary school program is not about integrals or logarithms. Everyone has learned the most important things, these simple rules are needed every day, so they are in the memory forever. And let complex calculations like functions, sines and tangents sink into long-term memory, if necessary, it can be refreshed. But quickly calculate which powder is more profitable to buy, we are always able to.
So back to second grade. Here’s an example.
- The order of actions is first the brackets: 8 – 6 = 2.
- Then the action over the line is 36 : 3 * 2 = 24.
- And then division at the end: 24 / 6 = 4.
But there’s another way, you know?
