† after 510BC. Chr.) there is already the dot before dash rule! Your parents will probably not have learned that in elementary school, today Hauptschule.
When does the rule do the trick?
The rule dot calculation before dash calculation, also called dot before dash for short, is a convention in the operator ranking of mathematics. It states that in a mathematical expression, unless parentheses are placed, multiplication and division must be performed before addition and subtraction.
Was it one counts first?
This rule says: First calculate multiplication and division and only then addition or subtraction. An example will now show how this rule is reliable (and how to get it wrong).
How does point before line calculation work?
This says that if you have several arithmetic operations in one term, you first carry out the point calculations, i.e. division and multiplication, then and only the line calculations, also addition and subtraction.
In which class do you have dot before dash?
The dot-before-dash rule is usually learned in grades 3 and 4 in elementary school. Because then you already master all basic arithmetic operations (addition, subtraction, multiplication and division) and can carry out corresponding chain or series calculations.
In what order is it calculated?
The order of calculation is therefore: bracket calculation. power calculation. Point calculation (multiplication and division)
What is charged first time or plus?
Using the example 2 + 3*5 we want to learn to understand the rule. The first arithmetic sign is a plus, the second a time, i.e. a higher-ranking dot sign. Therefore, you must do the point calculation before the line calculation.
Was the pikeperch dot before dash?
The rule dot calculation before dash calculation, also called dot before dash for short, is a convention in the operator ranking of mathematics. It states that in a mathematical expression, unless parentheses are placed, multiplication and division must be performed before addition and subtraction.
How do you calculate with brackets?
This is very simple: the number in front of the brackets is multiplied by all the numbers in the brackets. Example 4: In the next example, brackets are to be formed. In principle, the calculation looks the reverse of the previous calculation.
