How is the short term calculation process calculated?

Hello, the settlement of this problem is actually very easy to calculate, we divide by 4/3 into multiplication to calculate, and then by providing the factoring method to calculate, you can get the result very well.

That is, the original formula = 2018 7 4 - 2018 3 4

So when we encounter the fraction calculation of division, how do we transform the division of fractions?

Divide by a fraction and transform it by the reciprocal of the number.

Mention the common factor method.

And what is it?

In general, if the polynomial.

There is a common factor, and you can put this common factor outside the parentheses, and write the polynomial as the form of the product of the factor, this kind of factorization.

The method is called the common factor method.

So what are the other methods in simple calculations?

The second method is the parenthetical method.

1. When a calculation problem only has addition and subtraction operations and no parentheses, we can add parentheses directly after the plus sign, and the operation enclosed in the brackets turns out to be addition or addition, subtraction or subtraction. However, when parentheses are added after the minus sign, the operation enclosed in the parentheses is originally an addition, but now it will become a subtraction; It used to be subtracting, but now it is going to be added. (That is, when adding parentheses in addition and subtraction operations, the parentheses are preceded by a plus sign, the parentheses are unchanged, the parentheses are preceded by a minus sign, and the parentheses are changed.)

The third is another example of the splitting method

As the name suggests, the splitting method is to split a number into several numbers for the convenience of calculation. Such as: 2 and 5, 4 and 5, 2 and, 4 and, 8 and so on. Be careful not to change the size of the number in the split. For example:

Then there's the law of addition and associativity.

Note the use of the associative law of addition (a b) c=a (b c) to get a simpler operation by changing the position of the additive.

The above are some of the methods called simple operations, and they are also some of the more commonly used methods for doing math problems.

I hope the above knowledge points can be helpful to you.

2 6 11 1 3 11 + 2 6 11 7 112 6 11 11 14 + 2 6 11 11 72 6 11 (11 14 + 11 7).

Knowledge points examined:

1.Dividing by a number is equal to multiplying by the reciprocal of this number.

2.The application of the multiplicative distributive property can be used to make the calculation easy.

Extended Information: Multiplicative Distributive Property:

Adding (or subtracting) two numbers and multiplying another number is equivalent to multiplying the number by two additions (subtractions) respectively, and then adding (subtracting) the two products to give the same number.
