Write out the opposite numbers of 3, 0, - 1 and 1 / 2 respectively, mark the numbers and their opposite numbers on the number axis, and explain the position characteristics of each pair of opposite numbers on the number axis
-3,0,1,-1/2,
Symmetry about the origin
0 is itself, others are symmetric about 0...
The positions of rational numbers a and B on the number axis are shown in the figure: simplify | a + B | - | a-b|
It can be seen from the figure that if B < 0, a > 0, | B | > | a |, then | a + B | - | A-B | = - (a + b) - (a-b) = - A-B-A + B = - 2A;
If the distance between point a and the origin on the number axis is 3, and the distance between point B and the origin is 5, then the distance between a and B is 0______ .
If the distance from point a to the origin is 3, then a represents 3 or - 3; similarly, B represents 5 or - 5. Then the distance between a and B is 2 or 8
|5 | = | 5-0 |, his meaning on the number axis is the distance between the point of 5 and the origin
What is the meaning of the formula "a + 5"?
What is the meaning of the formula "a + 5"?
|The meaning of a + 5 | is the distance between point a and 5 or - 5
Why is it plus or minus 5? Because it's an absolute value
If the distance between point a and the origin on the number axis is 2, and the distance between point B and the origin is 5, then the distance between a and B is 0
7 or 3
3 or 7
3 or 7
Three or seven
The distance between the point of - 2.5 on the number axis and the origin is the distance between the point of 1.2 on the number axis and the origin
—2.5 1.2
As shown in the figure, a and B are two points on the number axis respectively. The number corresponding to point a is - 20, and that corresponding to point B is 100. (1) please write the number corresponding to point m whose distance is equal to that of point a and B; (2) an existing electronic ant P starts from point B and moves to the left at the speed of 6 units / second, while another electronic ant Q just starts from point a and moves to the right at the speed of 4 units / second The sub ants meet at point C on the number axis. Do you know the number corresponding to point C? (3) If the electron ant P starts from point B and moves to the left at the speed of 6 U / s, and the other electron ant Q just starts from point a and moves to the left at the speed of 4 U / s, let two electron ants meet at point D on the number axis. Do you know the number corresponding to point d?
(1) The corresponding number of m point is 40; (2) 28; their meeting time is 120 ÷ (6 + 4) = 12, that is, the movement distance of Q point at the same time is 12 × 4 = 48, that is, moving 48 units from number - 20 to number 28; (3) - 260. The time for P point to catch up with Q point is 120 ÷ (6-4) = 60, that is, the starting distance of Q point is 4 × 60 = 240, that is, moving 240 units from number - 20 to number - 260
As shown in the figure, a and B are two points on the number axis respectively. The number corresponding to point a is - 20, and that corresponding to point B is 100. (1) please write the number corresponding to point m whose distance is equal to that of point a and B; (2) an existing electronic ant P starts from point B and moves to the left at the speed of 6 units / second, while another electronic ant Q just starts from point a and moves to the right at the speed of 4 units / second The sub ants meet at point C on the number axis.

(3) If the electron ant P starts from point B and moves to the left at the speed of 6 U / s, and the other electron ant Q just starts from point a and moves to the left at the speed of 4 U / s, let two electron ants meet at point D on the number axis. Do you know the number corresponding to point d?
(1) The corresponding number of m point is 40; (2) 28; their meeting time is 120 ÷ (6 + 4) = 12, that is, the movement distance of Q point at the same time is 12 × 4 = 48, that is, moving 48 units from number - 20 to number 28; (3) - 260. The time for P point to catch up with Q point is 120 ÷ (6-4) = 60, that is, the starting distance of Q point is 4 × 60 = 240, that is, moving 240 units from number - 20 to number - 260
