It doesn t matter if the vassal relations are all negative

For some complex classes based on extended real numbers, we define an imaginary unit i that provides:

i2 = -1。

The complex can be represented as + bi, where it is called the real part and b will be called the imaginary part. When b = 0.

A + bi is a real number, and real numbers are so complex.

Complex numbers first appeared in the solution of equations, because the square root of a negative number could not be opened, so many formulas could not be solved, but these equations could not be said to be meaningless equations, and eventually introduced the concept of imaginary numbers, and the equation could be understood. Later, the number of negative numbers that needed to be imagined as having applications in almost all areas of mathematics would be further expanded, and now the complex is still the largest multi-set.

A positive number is a number above zero, and a negative number is a number below zero.

Positive numbers are greater than 0 and negative numbers are less than 0.

1: If you don't build it before, don't worry about it, you can't eliminate it, unless you remove all the cores of the country in your land, and the method is in 2.

2: If it's the version of ht, you can choose the national key areas around the provinces that have that country, so that those provinces are subject to the chain note, and then the provincial resolution will promote cultural unity, and the core of this and that country will be gone, you leave one and then establish a vassal country, the option must be affected by the national key areas, there must be a national core, there must be a core of the country that no longer exists in the province, if there are multiple cores in the local posture, the core of the country that does not exist will disappear, There is still a national core. If it's not a version, then you can only release the country first, and then declare war to cut off the land except the capital, and wait 5 years to declare war again, asking him to give up the core, and then vassalize.

3: If the relationship is too bad, or if your BB is too high, the strength becomes weaker, the vassal state may rebel, and it is generally necessary to form a military alliance. During the Reformation, it is necessary to always look at the vassal countries, if the vassal states change their religion, the relationship will plummet, so it is better to maintain the relationship, so that if there is a problem, it can be remedied.

4: Generally speaking, it is better to rule jointly, because there is a chance to inherit, if it is the same cultural group, the core will be automatically added when inheriting (version, the previous HT version has a core as long as the union inherits).。。However, it is more troublesome to pay attention to the relationship between the united countries and whether they have been defeated by the usurping rebels, but it is generally better to unite them.

The transformation of a polynomial into the product of several simplest expressions is called factoring the polynomial (also known as factoring). It is one of the most important identity variations in secondary mathematics, and it is widely used in elementary mathematics as a powerful tool for solving many mathematical problems. The factorization method is flexible and technical, and learning these methods and skills is not only necessary to master the content of factorization, but also has a very unique role in cultivating students' problem-solving skills and developing students' thinking ability.

Not necessarily, it depends on whether the bottom is greater than 1 or less than 1. Then it doesn't matter whether the positive number is greater than 1 or less than 1. For example: lg1=0 lg2= .

This statement means that the base of the logarithm is greater than 0 and less than 1, and the number of logarithms is greater than 1 or the base of the logarithm is greater than 1, and the number of logarithms is greater than 0 and less than 1, both of which are certain negatives!

Quantities with opposite meanings are positive and negative, as long as the signs are opposite, such as +4 and -8.

People often encounter various amounts of opposite meanings in their lives. If there is a surplus or a loss in the bookkeeping; When calculating the rice stored in the granary, sometimes it is necessary to record the grain, and sometimes the grain must be recorded.

For the sake of convenience, people consider the number of opposite meanings. Therefore, the concept of positive and negative numbers was introduced, and the surplus money into the grain was recorded as positive, and the loss of money and the grain was recorded as negative, and the positive and negative numbers were generated in the production practice.

Quantities of opposite meaning are two numbers with opposite signs, representing different positions relative to the datum point (0 point), and it does not matter whether their absolute values are equal or not.

The opposite number is the opposite of the positive and negative signs, and the absolute value must also be the same quantity.

When it comes to the numbers you are talking about, +5 and -4 are quantities in opposite senses, but they are not opposites.

5 and -5 are both quantities and numbers of opposite meanings.

Every 5 is a group.

Group Group Group Group

The first 240 numbers can be divided into 48 groups.

Group: 1+2+3+2+1 1+2+3+3+2+1-3 2 3+2 3-3 2 6-3

Group: 2+3+4+3+2 3 6-4

Group: 3+4+5+4+3 4 6-5

The sum of the top 48 groups is:

50＝（2+3+4+..49）×6-（3+4+5+..50) (2+49) 48 2 6-(3+50) 48 2 [(first + saga) number of items 2)].

Except for the different symbols, a pair of numbers that are the same is called an opposite number, that is, a quantity with opposite meanings is not.

Quantities of opposite meanings contain two levels of meaning: first, they have opposite symbolic meanings; The second is that they both denote a certain quantity (in terms they are not necessarily the same). For example, the water level of a reservoir is rising and the meter is falling, two quantities with the same meaning.

If the rising rice is recorded as +m, then the falling rice is the m.
