First, the understanding angle 1. Characteristics of an angle: a vertex and two sides (straight)

2. The size of the angle is related to the size of both sides, and has nothing to do with the length of both sides.

3. The angle of painting:

(1) Fixed Vertex.

(2) Draw a straight line from this point.

(3) Draw another side (at right angles, aim at the drawn side with the right angle side and draw a line along the other right angle side).

Second, the classification of angles:

1, understanding right angles: the characteristics of right angles,

2. Know acute angle and obtuse angle: acute angle is less than right angle, and obtuse angle is greater than right angle.

3. You can judge the right angle, acute angle and obtuse angle with a triangular ruler: overlap the vertex of the right angle on the triangular ruler with the vertex of the compared angle, then overlap one side of the right angle on the triangular ruler with one side of the compared angle, and finally compare the other side of the right angle on the triangular ruler with the other side of the compared angle. This line is a right angle, the inside is an acute angle and the outside is an obtuse angle.

4. Draw right angles, acute angles and obtuse angles.

1, number of copies × number of copies = total number of copies ÷ number of copies = number of copies.

Total copies/number of copies = number of copies

2, 1 multiple× multiple = multiple

Multiply1Multiply = Multiply

Multiply/Multiply = 1 Multiply

3. Speed × time = distance

Distance/speed = time

Distance/time = speed

4. Unit price × quantity = total price

Total price/unit price = quantity

Total price ÷ quantity = unit price

5. Work efficiency × working time = total workload.

Total amount of work ÷ work efficiency = working hours

Total workload ÷ working time = working efficiency

6. Appendix+Appendix = Total

And-one addend = another addend

7. Negative-negative = difference

Negative difference = negative

Difference+Minus = Minus

8. Factor × factor = product

Product ÷ One factor = another factor

9. Dividend bonus = quotient

Dividend = divisor

Quotient × Divider = Divider

One day, Xiaoming is going to pay the electricity bill. Suddenly, he found that in order to encourage electricity saving, the power company revised the previous charging method, which became: the monthly electricity consumption should not exceed 100 kWh, and it should be charged at 0.52 yuan per kWh; If the monthly electricity consumption exceeds 100 kWh, the electricity fee will be charged at 0.6 yuan per kWh for the excess. This can hurt Xiao Ming, you know, he knows nothing about mathematics! No way, she had to go home. Electricity consumption of Xiaoming 10 * *121kwh. How to calculate? At this time, Xiao Ming's sister Xiaohong came back. Seeing her brother's sad face, she asked him what happened ... finally figured it out, and Xiaohong decided to help this "math idiot". She sat down and patiently explained to Xiao Ming: "Our electricity consumption in one month exceeds 100 kWh,121-100 = 21(kWh) 21× 0.6 =/kloc. Where do you want to go! " "Oh, I see. I thought it was complicated! " Xiao Ming suddenly realized.

Finally, Xiao Ming finally paid the electricity bill smoothly. Seeing someone anxiously calculating how much money should be paid at the gate of the power company, Xiao Ming enthusiastically ran over and instructed him how to calculate. Xiao Ming thought happily: teaching others is not lazy! It seems that I have to "reinvent myself" to learn mathematics again in the future!

Grandpa took out a dirty calendar today, and some dates were unclear. Let me help him figure out what day the 27th is, because it's grandma's birthday. I looked at the calendar. It's too simple. The 22nd is Saturday, so 27-22=5, and the 27th is not Thursday. At this moment, my father is right. Let me try something else. So I began to think again: the 2nd is Sunday, and the difference from the 27th is 27-2=25 days, a week is 7 days, and 25÷7=3 (weeks) ... 4 (days), so I can also conclude that the 27th is Thursday. By the way, dad smiled and said, "You are great! Any clearly visible number can be calculated, and mathematics in life can be seen everywhere. "

Roman numerals are symbols representing numbers, which are combined to represent different numbers according to certain rules. When using this number, the number "0" is not needed. At that time, a scholar of the Roman Empire discovered the symbol "0" from Indian notation. He found it very convenient to use "0" for mathematical operations, and he also introduced the Indian method of using "0" to everyone. The Pope knew then. The Pope was very angry. He rebuked that the sacred number was created by God, and there was no "0" monster in the number created by God. So he ordered the scholar to be arrested, and his ten fingers were tightly clamped with a clamp, so that his hand was disabled and he could no longer write with a pen. In this way, "0" was banned by the ignorant and cruel Pope.

However, although the use of "0" is forbidden, Roman mathematicians still use "0" secretly in mathematical research regardless of the ban, and still make a lot of mathematical contributions with "0". Later, "0" was finally widely used in Europe, but Roman numerals were gradually eliminated.
