Solution: 1 2 3 4 5 6 ......99 100=(1 100) (100 zhi2)=101 50=5050 Analysis: dao1+100=101,2+99=101,3+98=101,4+97=101....Back to.... 50+51=101

There are a total of 100 2 = 50 back to 101, so the answer is 1 + 2 + 3 + 4 + ......Solution: 1 Zhi 2 3 4 Dao 5 6 ......99 100 = (1 100) (100 2) = 101 50 = 5050 Analysis: 1+100=101,2+99=101,3+98=101,4+97=101....Back to.... 50+51=101

There are a total of 100 2 = 50 101, so 1 + 2 + 3 + 4 + ......100=101×（100÷2

There are a total of 100 2 = 50 101, so 1 + 2 + 3 + 4 + ......100=101×（100÷2

Extended Materials. Easy calculation:

Simple arithmetic to make up integers, first exchange and then combine; A number is subtracted by a number in a row, which is equal to the sum of the next number minus the next number; A number is divided by several numbers consecutively, which is equal to the number divided by the next few products.

Several numbers and multiply a number, multiply and add respectively, multiply the difference by a number, multiply and subtract respectively, the same number is proposed, and the rest is enclosed in parentheses. Add more to subtract, add more to subtract, add less to add, and subtract less to subtract.

1+2+3+4+5+6+…Easy calculation of +100.

Solution: 1 2 3 4 5 6 ......99 100=(1 100) (100 zhi2)=101 50=5050 Analysis: dao1+100=101,2+99=101,3+98=101,4+97=101....Back to.... 50+51=101

1＋100＝101 2＋99＝101 3＋98＝101……And so on, then there are 50 101, 50 101 5050

Just add the largest number and the smallest number all the time.

5050, so finally get 5050!

1+2+3+4+5+6+…+100 for easy calculation of fourth-grade splits.

Hello: Dear, solution: 1+2+3+4+5+6+....+100 = (100 2) = 101x (100 2) sail flutter = 5050, so get 5050 in the end!

Pro, that is, the two numbers before and after are added to get 101, because there are a total of 100 numbers, and the two together will leave 50 pairs of nuclear hail sedans, and then 101 50 = 5050, so the final number is to stare at 5050!

Repentance: 1+2+3+4+5+6+...+100 = (1 + 100) + (2 + 99) + (Na Zao Zheng 3 + 98) + (4 + 97) + (50 + 51) = 101 (100 2) = 101x (Rock Good 100 2) = 5050, so finally get 5050! It's a little more accurate!

Dear, how else can I help you?

1+100=1012+99=101…In this way, each group is a group of two numbers, a total of 100 2 = 50 groups. 1 100 can be split into 50 logarithmic cores, each with an equal sum. You can use the equation of the difference series, and the sum of the changes is (first term + last term) x term number.

The method of adding the source and tail pairs of the first selling bridge can be used to calculate the neutral state.

There are a total of 100 digits here, which can be matched into 50 pairs, and the sum of each pair is 101.

Then we can use the meaning of multiplication to quickly figure out what the number is. The process is as follows:

101x50

Hello, I am honored to serve you, the following ** is my answer to your question, I hope it will help you!

1 100 out of 100 items.

1+99, 2+98....Void Clan....49+51 has a total of 98 items and 49 groups, and each group is 100.

There is also item 50 50 and item 100 at the end.

So Sislip 1+2+3......+100=100+50+100×49=5050

Observe first.

Only 50 and 100 did not come in pairs.

From 1 to 49 there are a total of 49 100 100 plus 100, which is exactly 50 100, plus a spine pin 50

In total, it is a finch infiltration:

50x100+50=5050

There will be no crack in the fourth grade, this can be done using the Gaussian formula, the first term plus the last term multiplied by the number divided by 2.

The main purpose of shampoo is to clean the scalp of excess impurities and oil, and now there are many types of shampoos on the market, with different merits or effects, oil control, dandruff detection, anti-shedding, etc. Choose a suitable and easy-to-use shampoo, not only in terms of efficacy, but also to see if it suits your hair type!

Recommend a few good shampoo brands for your own use.

This question needs to be disassembled to answer the Bright Field Slow question, which is known to be +97=100......By analogy, this question can be transformed into a spine

1+99)+(2+98)+(3+97)…Honoring the model....+(49+51)+50+100

Hello, this question is easy to operate: 1+2+3+4+5+6+.100=（1+100）*100/2=5050

Solution, the old Shen liquid inspection set a = 1 + 2 + 3 + 4 + + + + 100a = 100 + 99 + 98 + + + 2 + 1

then a+a=(1+100)+(2+99)+(3+98)++100+1) then 2a=101x100

a=101x100÷2=5050

Summing formulas using a series of equal differences.

(Dayuan 1+100)*50

I hope that the sedan chair can help you.

100 + 1 = 101 in a row, 2 + 99 = 101, there are 50 in total, 50 is used, 101 = 5050

Gaussian dismantles and harmonizes several numbers, which are arranged in a certain order, are a series of numbers. If the difference between any two adjacent numbers in the sequence is equal, we call the sequence an equal difference sequence. The first number is called the first term, and the last number of the chain is called the last term.

The difference between two adjacent numbers is called the tolerance, and the number of numbers in this sequence is called the number of terms.

Johann Carl Friedrich Gauss was a famous German mathematician, physicist, astronomer, and geodesy. One of the founders of modern mathematics, Gauss is considered one of the most important mathematicians in history and is known as the "Prince of Mathematics". Gauss, Archimedes and Newton are listed as the world's top three mathematicians.

His lifetime achievements were extremely fruitful, and the number of achievements named after his name "Gauss" reached 110, which is the most among mathematicians. He has made contributions to number theory, algebra, statistics, analysis, differential geometry, geography, geophysics, mechanics, electrostatics, astronomy, matrix theory, and optics.

Summary. 1+2+3+4+5+6+…+100=（1+100）+（2+99）+（3+98）+（4+97）+…50+51)=101*50=5050 or: 1+2+3+4+5+6+....+100=（1+00）*（100/2）=5050

1+2+3+4+5+6+…+100 for easy calculation of fourth-grade splits.

1+2+3+4+5+6+…+100 = (1 + 100) + (2 + 99) + (3 + 98) regret + (stalking 4 + 97) + ...50+51)=101*50=5050 or: 1+2+3+4+5+6+....+100 = (1 + 00) Bezena * (100 2) = 5050

Or: 1+2+3+4+5+6+...+100=（1+100）*（100/2）=5050

There are a total of 100 numbers, the sum of the first positive number and the first number of inverted dry chain reeds is 101, and the sum of the second positive number and the second penultimate number is also 101, and so on, there are 50 101s, so the simple calculation is as follows: (1+100)x50=50+5000=5050

It's not a split, it's an addition of the beginning and the end.
