Draw a little more delicately, that's the effect, I've painted it.

I can't see **--- only two lines of words.

Is this from elementary school???

Definition of multiplication: the addition of several identical numbers.

Definition of division: to divide into several parts of the same number'The same number'is the dividend, so 2*(1+1) is equivalent to (1+1)+(1+1), i.e. (2*1)+(2*1).

2 1 + 2 1 is equivalent to dividing a 2 into two parts with the same number 1 (one of which is denoted as a), then dividing a 2 into the same way (one of which is denoted as b), and then adding each of the two parts (i.e., a+b).

But 2 (1+1) thinks that the priority of the symbol should be calculated first (), so it is equivalent to 2 (1*2), i.e. 2 2, that is, 2 is divided into a share with the same number 2.

Don't forget to put a bounty!! Hehehe!!

2*(1+1): A wants two apples, and B wants two apples, so a total of 4 apples are needed, which is the multiplicative distributive property.

2 (1+1): Now that there are two apples, how many can A and B get? 1 2 1 + 2 1: Give A two apples, give B two apples, a total of four apples to connect life, think slowly.

Because multiplication has a distribution rate while division does not.

This is the multiplicative distributive law of mathematics, but there is no division distributive law, so only multiplication can do this!!

In the multiplier formula, it can be called a multiplier....

However, in the divisor formula, it is divided into divisor and dividend, such as a b a b b = (a a) b where a is the divisor b is the dividend, b can be combined when b is the same, and b cannot be combined when a is the sameSo it's a common sense mistake to divide 2 (1 1) into 2 1 2 1 1 in reverse reasoning, so it's not a problem....

The area of the original shadow part = S large fan + S small sector - S rectangle = *(6 2 + 4 2) 4-6 * 4 = 13 -24, now only the part of the shadow area removed below can be required, the area of this part = the fan area with arccos2 3 arc center angle - s = *6 2 2 * arccos2 3-1 2*4*v(6 2-4 2).

18arccos2 3-4v5, the area of the shadow sought = (13 -24) - (18arccos2 3-4v5).

Here's a suggestion: your diagram can be made clearer.

Don't be nervous, think twice, communicate more, consult your peers, show nervousness will not make people think that you are active and diligent, calm and communicate more to ask more questions, in order to do things well. It also makes people think that you are honest and helpful, who is born to know?

That's when you think about the problem, worry too much, don't think too much, you might as well give yourself a little time every day to look at the scenery, slowly learn to adjust your mentality, learn to give up.

It's too careless, be bold, be careful, do more things outside, and have more experience, and you'll be fine.

It shows that you seem to be simple, and your things are not simple!!
