　　原标题：王毅会见美国国务卿克里
　　新华社慕尼黑2月12日电 中国外交部长王毅12日在慕尼黑会见美国国务卿克里。
　　王毅表示，前不久习近平主席应约同奥巴马总统通了电话，习主席就下阶段中美关系提出了重要指导意见。希望双方共同努力，认真落实两国元首达成的共识，确保两国关系保持健康稳定发展。
　　王毅与克里重点就朝鲜半岛局势进一步交换了意见。王毅表示，朝鲜再次进行核试验并使用弹道导弹技术发射卫星，连续违反联合国有关决议，严重冲击国际核不扩散体系。为此，中美双方都同意加快在安理会的磋商进程，尽快达成一份新的决议，采取有力和有效措施阻遏朝鲜进一步发展核、导计划。同时，中方重申制裁不是目的，我们的共同目标还是要一起想办法把半岛核问题重新拉回对话谈判的正确轨道，这完全符合包括中美在内各方的利益。克里对此表示同意。
　　王毅还就美国可能在韩国部署“萨德”反导系统表明了中方的反对立场，要求美方务必慎重行事，不要借机损害中国的安全利益，也不要给本地区和平稳定增加新的复杂因素。

Arithmetical operations
arithmetical[7AriW5metikEl]adj.()
arithmetic[E5riWmEtik]n.,
operation[7CpE5reiFEn]n.,

operate[5CpEreit]v.,
opera[5RpErE]n.
Addition & an operation of finding a sum of some numbers:
11 + 6 = 17. &Here 11 and 6 & addends,& 17 & the sum.
addition[E5diFEn]n., , , , add+-ition
addend[E5dend]n.
sum[sQm]n.,
If addends are changed by places, a sum is saved the same:
11 + 6 = 17 and 6 + 11 = 17.
Subtraction & an operation of finding an addend by a sum and another addend:
17 & 6 = 11.& Here 17 is a minuend,& 6 & a subtrahend,& 11 & the difference.
subtraction[sEb5trAkFEn]n.[],

difference[5difErEns]n., , , , [], adj.[], []dif- =dis- +fer + -ence
Multiplication.&To multiply one number&n ( a multiplicand ) by another m ( a multiplier ) means to repeat a multiplicand&n as an addend m times.
multiply[5mQltiplai]vt., vi; , ; ;((multi-

multi-[5mQltI][]
multiplicand[7mQltipli5kAnd]n.
The result of&multiplying is called a product.
result[ri5zQlt]n. (re- +sult-salire)
product[5prCdEkt]n., ,
The operation of multiplication is written as:&n x m or n & m .
written[5ritn]vbl.write
For example, 12&x 4 = 12 + 12 + 12 + 12 = 48.
for example adv.
In our case 12 x 4 = 48 or 12 & 4 = 48. &
Here 12 is a multiplicand(), 4 & a multiplier, 48 & a product.
If a multiplicand&n&and a multiplier&m are changed by places, their product is saved the same:&
12 & 4 = 12 + 12 + 12 + 12 = = 48& and&& 4 &12 = 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 = 48.
Therefore, a multiplicand and a multiplier are called usually factors or multipliers.
therefore[5TZEfC:]adv.,
multiplicand[7mQltipli5kAnd]n.
multiplier[5mQltiplaiE]n.
factorMathematics One of two or more quantities that divides a given quantity without a remainder:
Division & an operation of finding one of factors by a product and another factor:
division[di5viVEn]n., , ,
divide[di5vaid]v., , ,
48 : 4 = 12.
Here&48& is a dividend,& 4 & a divisor,& 12 & the quotient.
dividend[5dividend]n.
divisor[di5vaizE]n., , ,
quotient[5kwEuFEnt]n.,
patient[5peiFEnt]n.,
At dividing integers a quotient can be not a whole number. Then this quotient can be present as a&fraction.
fraction[5frAkFEn]n., , fracfract
If a quotient is a whole number, then it is called that numbers are divisible, i.e. one number is divided without remainder by another.
Otherwise, we have a division with remainder.
otherwise[5QTEwaiz]adv., , , adj.,
otherwise other+-wise
remainder[ri5meindE]n., , , []
remain[ri5mein]vi., , ,
For example, 23 isn&t divided by 4 ; this case can be written as:& 23 = 5 & 4 + 3.& Here 3 is a remainder.
Raising to a power. To raise a number to a whole (second, third, forth, fifth etc.)
power means to repeat it as a factor two, three, four, five and so on.
and so on& adv.
The number, repeated as a factor, is called a base of a power; the quantity of factors is called an index or an exponent of a power; the result is called a value of a power.
A raising to a power is written as:
3 5& = 3 & 3 & 3 & 3 & 3 = 243 .
Here& 3 & a base of the power,& 5 & an exponent (an index) of the power,& 243 & a value of the power.
base[beis]n., ,
exponent[eks5pEunEnt]n., , , ,
index[5indeks]n., []
The second power is called a square, the third one & a cube.
square[skwZE]n., ,
cube[kju:b]n.,
The first power of any number is this number.
Extraction of a root & an operation of finding a base of a power by the power and its exponent:

The second degree of square root isn&t written:
Addition and subtraction, multiplication and division, raising to a power and extraction of a root are two by two mutually inverse operations.
