Primary 1 Mathematics!! HELP！！

The result is 31, and from the four known figures, the circle, square, and triangle each represent three numbers. And the position of the two figures in each diagram represents a certain addition and subtraction relationship.

2. Further analysis can be known: square = 1, circle = 2, triangle = 5.

When the outer figure represents a number more than the inner figure represents a number of hours, the two numbers are added together. As shown in the first figure: 1+2=3.

When the outer figure represents a larger number than the inner figure, the larger number is subtracted from the smaller number. As shown in the second figure: 2-1=1.

3. From the above rules, it can be seen that the result of the last graph is the addition and subtraction of triangles and circles. Because the triangle is larger than the circle, the result is 5-2=3.

It's a bit wordy, I hope it helps

Very simple. Figure 1 and Figure 2 both have circles 3-2 = 1 square: 1

Circle: 2 Triangle: 5 Answer 3

What a bad topic, and suddenly I found out that I had become stupid.

You can just kill your teacher! He may be insane!

Stipulation: The inner and outer figures are followed by the outer figure minus the inner figure.

Those who do not come into contact are the outer and inner figures.

Then the square is 1, the circle is 2, and the triangle is 5, then if the last picture is not connected, it is 7, and the connection is 3

From the question, it can be seen that one apple is equal to two peaches, and two pears are equal to six peaches, so one pear is equal to three peaches.

2 apples equals 4 peaches 1 pear is an apple and apples equals 3 peaches, so one pear equals 3 peaches.

6 apples = 12 peaches; 4 pears = 6 apples; Therefore: 1 pear = 3 peach selection: b

3 ten, 3 ten, 4 = 10 (only).

The meaning of the title is: 3 birds staying in the tree and 10 birds flying away + 4 other birds flying away, how many birds are there?

solution, 3+3+4

10 This is a basic arithmetic operation, just add it up.

There were already 6 of them, but three of them were going to go, and four of them were coming, so it should be.

6 3+4=7, you're right.

It should be 3+3+4

10 Thank you for clicking to adopt.

The midpoint of the inner arc of the crescent moon is tangent to make a straight line, divide the crescent into 3 parts, and then make another straight line to intersect with the front line through the sharp corner of the cut out, and divide each part into two parts, as shown in the figure.

The graph is a large graph (month) although there are 5 charts on the chart

Can you cut it horizontally like a cake?

That is a vertical knife and a knife in the middle.

Two lines don't have to be straight lines, do they? Try.

The two straight lines are not parallel to each other and intersect inside the moon, and each of the two straight lines separately divides the moon into three parts.

I didn't say you couldn't use curves.

Use two lines, one n and one inverted v.

Correct Answer:

4+4=8 (trees).

8+8=16 (trees).

A: Uncle Goat harvested a total of 16 cabbages.

Analysis: Uncle Goat gave a total of: 4 + 4 = 8 trees.

The rest is as much as what was sent, that is, the rest is also 8, so Uncle Goat received a total of 8 + 8 = 16 cabbages.

This question should be very simple, there are a total of 16 cabbages, and if you send out 8 cabbages, then there will be 8 white left.

It's best to ask a teacher in person. You can think of the reduced surface area as a curved rectangle, the length is the circumference of the bottom surface of the cylinder, the width is 2 centimeters, and the area is, so the length is: divide by 2 equals centimeters, centimeters is actually the circumference of the bottom surface of the cylinder, calculate the radius is divided by 2, and then divide, and the result is quickly calculated.

The circumference of the base surface of the cylinder = cm.

The radius of the base surface of the cylinder = cm.

(The base radius of this cylinder is 4.)

Set: The radius of the bottom surface is x.

squared) 2=

Kind of forgot, 8 hanging.

You set it up first.
